----
They are separating at the rate of 40+30 = 70 mph
----
time = distance/rate
time = 245/70
time = 3.5 hours

let x=distance train traveling east
245-x=distance train traveling west
Travel time=distance/speed (same for both trains)
x/40=245-x/30
30x=9800-40x
70x=9800
x=140
Travel time=140/40=3.5 hrs
how long will it take for the trains to be 245 miles apart? 3.5 hrs
