A train leaves the station at 4:00pm traveling west at 50 miles per hour. On a parallel track, a second train leaves the station at 8:00 Pm traveling west at 70 mile per hour. At what time will the second train catch up with the first?
-------------
At 8, the 1st train is 200 miles away (4*50)
The 2nd train gains in the 1st at 20 mi/hr (70 - 50)
d = r*t
t = d/r = 200/20
t = 10 hours to catch up
8 PM + 10 hours = 6AM

50*4hrs=200 mile lead.
70-60=20mph overtake speed
200/20=10hrs to catch
=6am next day
