Trains will meet after 8.33 hours.

sA = 70, sB=50.
Relative speed = 70+50=120
Total time = 1000/120=8.33 hours

1) Both are not starting at the same time.
2) sA travel 35 miles before sB starts in 30 mins( 10-9:30)
3) So @10:00 the distance remaining is 965
4) sA = 70, sB=50.
Relative speed = 70+50=120
Total time = 965/120=8.041 hours from 10:00 am = 6:02:30 pm
