The diesel train traveled for 20 hours, 13 before the other and 7 hours both. Its speed was x
The freight train traveled for 7 hours and its speed was x+50
The distance is 20x+7(x+50)=20x+7x+350=620
27x=270
x=10 mph diesel
x+50=60 mph freight
The diesel train went 130 miles before the freight train left and another 70 miles in 7 hours=200 miles.
The freight train went 60 mph*7 hours or 420 miles
sum is 620 miles.
