Trains A & B are traveling in the same direction on a parallel tracks. Train A is traveling at 60 mph and train B is traveling at 80 mph. Train A passes a station at 5:15 PM. If train B passes the same station at 5:30 PM, at what time will train B catch up to train A?
When will train B catch up with train A?

algebra 
Damon,
train A goes t hours
train B goes (t.25) hours
distance is the same
so
60 t = 80(t.25)
solve for t in hours
add that to 5.25 to get time in hours
convert fractional hours to minutes
