How do you rearrange the formula for acceleration to find the time taken for the change?

Here is the question:

A cheetah is moving at 5m/s. It can accelerate at 10m/s^2. How long will it take to increase its speed to 20 m/s?

HEELP!! THANK YOU :)

Acceleration= Change in velocity / Time taken

Put it into a triangle formation;

      V 
A         T

T=Time takenV=Change in velocity

Put your finger over what you are trying to work out, in this question it is time taken.

You would do Change in velocity/Acceleration

15/10=0.667seconds

Hope this helps :)
