Answer by Greenfinch(383) (Show Source): You can put this solution on YOUR website!
If they are 400 miles apart and meet after 4 hours, they are moving towards each other at 100 miles / hour
The speed of one is X and the speed of the other is X + 20
So 2X + 20 = 100
X= 40 and the other is 60 miles/hour
