Question 193691
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. 
Your help is appreciated. 
-----------------------------------
Given DATA:
distance = A miles ; time = x hrs ; rate = d/t = A/x mph
-------------------------------------
Time Problem DATA:
distance = B miles ; rate = A/x mph 
Equation: 
Time to travel B miles  = d/r = B/(A/x) = Bx/A hrs
