To find the local time in West Africa (at 20°W longitude) when a program was broadcast from Mumbai at 7:30 p.m., we need to calculate the time difference between Mumbai and West Africa. 1. Mumbai (72.8°E) to Prime Meridian (0°): Mumbai is ahead of the Prime Meridian, so we need to subtract the corresponding time difference. Since every 15 degrees of longitude corresponds to a time difference of 1 hour, Mumbai is approximately 4 hours and 51 minutes ahead of the Prime Meridian. 2. Prime Meridian (0°) to West Africa (20°W): West Africa is behind the Prime Meridian, so we need to add the corresponding time difference. Since every 15 degrees of longitude corresponds to a time difference of 1 hour, West Africa is 20°W, which is approximately 1 hour and 20 minutes behind the Prime Meridian. Now, we add the time difference between Mumbai and the Prime Meridian to the time difference between the Prime Meridian and West Africa: 4 hours and 51 minutes (Mumbai ahead of Prime Meridian) + 1 hour and 20 minutes (West Africa behind Prime Meridian) = 6 hours and 11 minutes. So, the local time in West Africa when the program was broadcast from Mumbai at 7:30 p.m. would be approximately 1:19 p.m. on the same day. Sir can you tell ans of this ques
so to sum up the video: calculate: time to longitude conversion ________________________________________ step 1) identify in question where west longitude, meridian and east longitude are compared to each other. step 2) find the time difference = if west time is given substract the west time with the east time ( ensure all are in the standerd 24hr time not 12hr one) / if east time is given add the east time with west time. step 3) conversion from hour to min = turn the found number in hr and min to only min. step 4) as 4 min= 1 longitude, calculate the value of found min into longitude (ans) calculate: longitude to time conversion ________________________________________ step 1) step one of the previous method. step 2) find the time difference = if west longitude is given add the west and east longitude/ if east longitude is given substract. step 3) multiply previously found value with 4 step 4) convert min into hour step 5) if, the question demands the local time of the specified place then add( if the asked place is east) and substract ( if the asked place is west) the found time in step 4. thankyou for the video, it ensured me 10 marks in my gs exam and this is a little short summery for people with further confusion. beware: I am also a class 10 examiner so i dont know more than i've been taught if i made any mistakes, inform me. good day.
This is the first time someone did explained the icse syllabus very well cuz other teachers mostly focus on NCERT topics and I'm so glad that someone explained it soo well!!!!👍 Hatsss off to uuu!! Ourrr saviour!!✨
I'm in grade 11th cbse, i have geography and i have same numericals in my syllabus and this video is so useful even to me really great explanation sir , i studied my whole 10th grade from you best youtube channel ever!!! i recommend it to everyone ✨️✨️
Sir mene hi isse bola acha se comment kro infact mene hi isse video ka link bheja apne bola tha And ye mujhe bol rha tha kis budha ka video bhej diya 😢
Your teaching skill is very nice sir👍🏻 literally I never seen a teacher like you who teach geography online you are the best teacher 🤗 really you are like a game changer. Thanks sir😊 please upload more videos.
12:49 Sir, the in the first question, The time difference is 138.75 degree and not the longitude of the place. So, after subtracting, 138.75 - 88(From Chicago's longitude to Prime Meridian) = 50.75 degree. Therefore, the longitude of the place shall be: 50.75 degree East. i.e. 50°45' (Thanks @VampyboiFTW ) Is the answer right sir?
Sir, tomorrow is my exam and I started crying because I wasn't getting this geo numericals at all and then I remembered that I do have Tarun Rupani sir... Thank you so much for your efforts 😇
I can't tell you sir how much this has helped me for my competitive exams.. me toh literally pareshan ho gayi thi k kaise nikalu iska time and degree but fir dhundte dhundte aap ka channel show kia... all thanks to you sir.. pranam n love from odisha❤️🙏
Sir u wont believe it but tomorrow is my exam and before watching this video i had no clue about time sums, thanku sir. We need more teachers like u who have the patience to explain every single thing giving full energy to it without wanting to complete syllabus quickly! Again, Thanku so much sir!!!
TEAM TARUN RUPANI Please respond it Sbhi phla hi question galat siikh rhe h Sir first question me aapne 138.75 East direct 88 degree West me add kar diye h l think ye 138.75 - 88= 50.75degree Then 0 degree +50.75degree East Hence longitude of place is 50.75degree East hoga
Thank you soooo much sir... It is an amazing explanation.... All my doubts are cleared.... Such excellent explanation videos specially of ICSE board are very rare on TH-cam. Thankyou sir 🙏
Thank you so much sir ❤ for making such a detailed video for us . I don't have much friends but I share your videos to my few friends and they feel that your videos are very helpful❤ thank you so much for teaching so well and you deserve to be the Google sir of ICSE🎉
Literally sir i was so upset that how to do ch- geographic grid and how to calculate the time, but you explained it in just one shot. Thanku very much sir, I would definitely share this video in my friends whatsapp group.
Tysm...sir m so thankful of having a teacher like you here out...god bless you sir...tomorrow is my exam nd M watching it now as a beginner nd now M doing PHD in Calculating time 😂

Sir can you tell ans of this ques
Tomorrow is my exam just because of you sir I understood how to do it Tqsm for explaining so well
Same bhai
Us bro us
Same bhai
Same bro
same brdr 😅
so to sum up the video:
calculate: time to longitude conversion
________________________________________
step 1) identify in question where west longitude, meridian and east longitude are compared to each other.
step 2) find the time difference = if west time is given substract the west time with the east time ( ensure all are in the standerd 24hr time not 12hr one) / if east time is given add the east time with west time.
step 3) conversion from hour to min = turn the found number in hr and min to only min.
step 4) as 4 min= 1 longitude, calculate the value of found min into longitude (ans)
calculate: longitude to time conversion
________________________________________
step 1) step one of the previous method.
step 2) find the time difference = if west longitude is given add the west and east longitude/ if east longitude is given substract.
step 3) multiply previously found value with 4
step 4) convert min into hour
step 5) if, the question demands the local time of the specified place then add( if the asked place is east) and substract ( if the asked place is west) the found time in step 4.
thankyou for the video, it ensured me 10 marks in my gs exam and this is a little short summery for people with further confusion. beware: I am also a class 10 examiner so i dont know more than i've been taught if i made any mistakes, inform me. good day.

Is the answer right sir?
And sir, online solutions say the answer is 50° 45′ E... And I got 50° 75′ E... So where have I gone wrong?
@@ThejasRP its not 50°75' its 50.75° = 50°45' (since we have only 60 minutes we have to take 75% of 60 = 45)
@@vampyboiftw Oh, Thanks!
@@vampyboiftw hey what if I write only 50.75 is it wrong or right
Can any one explain me y we subtract 88 from 138.75 when the time is fast

138.75 - 88= 50.75degree
Then
0 degree +50.75degree East
Hence longitude of place is 50.75degree East hoga
