You can put this solution on YOUR website!
r = speed of one of the trains, the slower train.

________________speed_____time_____distance
Either train_______r_________2________r*2
Other train________r+5_______2________(r+5)*2
TOTAL______________________________200-50=150

Solve for r:
highlight%282r%2B2%28r%2B5%29=150%29

To finish, also compute r+5.
