**Reiny**, Sunday, November 13, 2011 at 1:03amlet the distance be x miles

time for first train = x/40

time for second train = x/50

x/40 - x/50 = 1/2

times 200

5x - 4x = 100

x = 100

Distance is 100 miles

check: to go 100 miles at 40 mph takes 100/40 hrs = 2.5

to go 100 miles at 50 mph takes 100/50 = 2hrs.

Does it take 1/2 less ? YES
