Question 223941: Hello,
I do not know how to answer word problems involving trains traveling at a certain rate of speed, thus wondering when they will meet. See below:
Train A and B are traveling together on a parallel track. Train A is traveling at 60 mph and Train B is traveling at 80 mph. Train A passes the train station at 2:20 pm. If Train B passes the station at 2:35 pm at what time will Train B catch up with Train A?

I know the following equations will help but i dont know how to incorporate them:
d=rt
d=ST
S=D/T
T=D/S
??? Thanks

train A is 15 mi ahead of train B
overtake speed is 20 mph
15/20=.75 hr=45 min
2:35+45=3:20 pm
