I have figured the equation for this word problem Train A is traveling parallel to Train B. Train A is traveling at 100 mph and Train B at 110 mph Train A passes a station at 1:15pm Train B passes the same station at 1:45pm When will Train B catch up with Train A? I have 100*t=110(t-1/2) then t=110t-55 so t=11/2 and now I am stuck could someone help me out here?
