<PRE><B>Question 810772</B>
Ricky drove from Town A to Town B in 3 hours. His return trip from Town B to Town A took 5 hours because he drove 15 miles per hour slower on the return trip. How fast did Ricky drive on the trip from Town A to Town B? 
-------
A to B DATA:
time = 3 hrs ; rate = x mph ; distance = r*t = 3x miles
-----
B to A DATA:
time = 5 hrs ; rate = x-15 mph ; distance = r*t = 5(x-15) = 5x-75 miles
--------
Equation:
distance = distance
-------------
3x = 5x-75
2x = 75
x = 37.5 mph (rate from A to B)
