Question 595236
Trains A and B are traveling in the same direction on parallel tracks.
 Train A is traveling at 60 miles an hour and train B is traveling at 64 miles an hour.
 Train A passes a station at 12:20 a.m.
 If train B passes the same station at 12:50 a.m., at what time will train B catch up to train A?
:
From the given information, we know that Train B is half hour behind A at 12:20 am
therefore Train B is:
.5 * 64 = 32 miles behind Train A at that time.
:
Let t = time required for Train B to catch Train A
:
Write a distance equation; dist = speed * time
:
Train B dist = Train A dist + 32 mi
64t = 60t + 32
64t - 60t = 32
4t = 32
t = 32/4
t = 8 hrs for B to catch A 
:
12:20 + 8 = 8:20 am for B to catch A
