<PRE><B>Question 573813</B>
Trains A and B are traveling in the same direction on parallel tracks. Train A is traveling at 40 mph and train B is traveling at 48 mph. Train A passes the station at 7:15 pm. If train B passes at 7:30pm, at what time would train B catch up to train A? 
-----------------------------
Train A DATA:
rate = 40 mph; distance = x miles ; time = d/r = x/40 hrs
-------
Train B DATA:
rate = 48 mph ; distance = x miles ; time = d/r = x/48 hrs
------
Eqaution:
A time - B time =  1/4 hr
(x/40) - (x/48) = 1/4 hr
--------
[48x - 40x)/(40*48) = 1/4
----
8x = 10*48
x = 10*6
x = 60 miles
