You can put this solution on YOUR website! Train A and B are traveling in the same direction on parallel tracks.
Train A in traveling at 40 miles per hour and train B is traveling at 50 miles per hour.
Train A passes a station at 3:15 P.M.
If train B passes the same station at 3:27 P.M., at what time will train B catch up to train A?
-------------------
Train A DATA:
rate = 40 mph ; time = x hrs ; distance = 40x miles
------------------------------------------------------
Train B DATA:
rate = 50 mph ; time = x-(1/5) hr ; distance = 50x-10 miles
------------------------------------------------------
Equation:
distance = distance
40x = 50x-10
-10x = -10
x = 1 hr
---
Time B will catch up to A: 3:27 pm + 1 hr = 4:27
