From the last question. I did this and believe that is the way too
S=kt/v^2
S=(3t)k/v^2/4
=> 3kt×4/v^2
S=12kt/v^2
Percentage increase =
(12kt/v^2 - kt/v^2 All divided by kt/v^2)×100%
(11kt/v^2 ÷kt/v^2)×100%
(11kt/v^2 ×v^2/kt)×100%
v^2 cancels v^2
(11kt/kt)×100%
11×100%
Ans.=1100%

Thanks now I know how to get the % increase!

[@amanbhoomik7939]

@@raknos13 the correct formula that should be used here is: [(new-original) divided by original]x100

Your annotations at the bottom of the screen crack me up. Thank you for sharing your knowledge and your humor.

[@cardiyansane1414]

One of the things I appreciated the most about your videos is that we were never just thrown in head first into a topic; the clear, concise explanation and the gradual increase in difficulty is what kept neanderthals, such as myself, audaciously going. Excellent work Phillip !

Every minute I spend on your channel, I learn something new and great. You're a great tutor.

Hi Philip! Thank you so much for helping me score well in my quants section, I was super underconfident since math isn't my strong suit but your videos helped me understand the concepts really well!

Dear philip,
I just watched all your quant videos. It was fantastic and I learned a lot.
Just one question: do you think there are still subjects on the GRE that you have not covered yet? If so, can you tell us the subjects so that I could search for them?
Your amazing
