Example:- A car travels 1km with speed of 80kmph Than time = 1000(metre)/80(kmph) = 12.5(second) Distance = 80(kmph)x12.5(second) =1000(metre) Speed = 1000/12.5 =80
Wrong.... Car is going with speed of 1.33 km per minute... 0.022 km per second... It takes 45 seconds to travel 1 km... A car travels 1 km with speed of 80kmph Than time in hours (to travel 1km) = 1 km / 80 km = 0.0125 hrs. = 0.75 minutes = 45 seconds Proof: 45 seconds - 1 km 90 seconds - 2 kms 180 seconds - 4 kms 3 minutes - 4 kms 30 minutes - 40 kms 60 minutes - 80 kms 1 hour - 80 kms Thus 80 kms/hour Distance = 80(kmph)x0.0125 =1 km Speed = 1km/0.0125hrs =80 kmph NOTE: You divided 1000 meters with 80 kms.... It should be either 1000/80000 or 1/80
Tip : draw a triangle and label it with D at top and bottom S and T when u need speed, shade s in the triangle, Leaving u with D over T same for time taken.
It really isn’t that simple though. Let’s say we are calculating time. If you are calculating time with a distance equaling 84nm and a ground speed of 139----the formulas of distance divided by speed will be equal to 84/139=.604 times that by 100 and you get 60.4 percent which is basically 60 percent of a min. Not an answer obviously. You then have to take .60 which is your calculation and multiply it by 60 which is how long a min is That gets you an answer of 36 min. These formulas only get you most of the way there and a video like this may be very misleading to those who think that’s the answer.
Thank you very much i really need this for my EXAM tommorow❤
Thanks a lot for my,, 😊
Very nice video maam❤
Thank you so much ❤❤❤❤❤❤❤❤😢😢😢
Example:-
A car travels 1km with speed of 80kmph
Than time = 1000(metre)/80(kmph)
= 12.5(second)
Distance = 80(kmph)x12.5(second)
=1000(metre)
Speed = 1000/12.5
=80
How did you get 12.5

Wrong.... Car is going with speed of 1.33 km per minute... 0.022 km per second... It takes 45 seconds to travel 1 km...
A car travels 1 km with speed of 80kmph
Than time in hours
(to travel 1km) = 1 km / 80 km
= 0.0125 hrs.
= 0.75 minutes
= 45 seconds
Proof:
45 seconds - 1 km
90 seconds - 2 kms
180 seconds - 4 kms
3 minutes - 4 kms
30 minutes - 40 kms
60 minutes - 80 kms
1 hour - 80 kms
Thus 80 kms/hour
Distance = 80(kmph)x0.0125
=1 km
Speed = 1km/0.0125hrs
=80 kmph
NOTE: You divided 1000 meters with 80 kms.... It should be either 1000/80000 or 1/80

Better than my school😂
You can just use the triangle ...
Ty I need this for my entrance exam later
thanku so much❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤😊
Thank you
Distance(s) = ut +1/2 at^2
Yes
But the music of senorita ❤❤❤❤ I love it ❤❤the music 🎶 the song is senorita ❤❤❤
ikr!
@@ValRiddle okk so,What can I do???
Thanku mam ji
Thank-you it will help me a lot for my science viva tommorow 😊😊😊😊😊
THANKYOU❤❤❤❤❤❤
A good idea about physics
Thanks
Why is no ome talking about how satisfying the handwriting is
Mam plz tell difference between speed and average speed
Thankyou mam for us this formula
Velocity=u+at
Thankyou so so so much ❤❤❤❤❤
Thank you very much i really need this for my Exam tomorrow of maths ❤💟
thank you so much !!! :)
Thanks so much I need it for my exam tomorrow
Thank you so much ❤❤❤
thank you I really needed this for my exam on Wednesday
Thank you❤❤
Thank you i am having a big exam tomorrow containing 400 questions wish me a good luck 🤞🍀❤❤
All formulas of average and speed please
I love it when you call me senurita I
😳😳
I literally needed this for my exam
Thanks❤
Thanks u bro 🙏❤
Tanks ❤
Kis kis ka kal exam hai like karo😂❤
Mera exam aj he
Myyy😢😢😢😅😅
I will use them later
Tip : draw a triangle and label it with D at top and bottom S and T when u need speed, shade s in the triangle,
Leaving u with D over T same for time taken.
Thanks 🎉🎉
Pov - u r class 11th jee aspirant 😅
👍🏻👍🏻👍🏻👍🏻👍🏻
Thank you for leaning it😊
DST is easy to remember 😊
Same distance = 2xy/x+y
Follow ako sayo ate ha
Thank you so much 😊😊😊 you are super

Thankyou mam
ok
Physics related to math
Nice 😊😊
thanku shalini di
Tune b bdiya h 😅
Today is my exam😂

Don’t we learn this in 4th grade? I learnt that in 4th.
Find the SIX
btw
thank you so much I dont understand how it is done but you helped me so much thanks ❤❤❤
Avg speed formula is incorrect, it is 2ab/a+b

Sir time or distance dono hi nhi diya ho to kaise solve karenge
There is two formula for average speed
which one is times or devide
Blud learn English first before kinematics
But average speed jaisa dikhta hai vaisa hota nhi 😒😒
Average speed ka or koi formula nahi hai
wait average speed importmant 2*a*b/a+b ?
Vahi to Mai bhi soch raha thha.. tabhi comments check kiye
Thanks
Thanks
