if a person can run A miles in x hours, how long will it take the person to run B miles at the same rate?
:
Find the rate of speed if you run A mi in x hrs:
rate = A%2Fx
:
Find the time to run B mi at a rate of A%2Fx
Time = B%2F%28A%2Fx%29
invert the dividing fraction and multiply:
Time = B * x%2FA = %28Bx%29%2FA
