Two cars started from the same point and traveled on a strai

Two cars started from the same point and traveled on a straight course in opposite directions for exactly 2 hours, at which time they were 208 miles apart. If one car traveled, on average, 8 miles per hour faster than the other car, what was the average speed for each car for the two hour trip?

Solution

208/2=104
104=X+X+8
104-8=2X
2X=96
X=96/2
X=48 IS THE SPEED OF THE SLOWER CAR.
48+8=56 IS THE SPEED OF THE FASTER CAR.
PROOF:
2(48+56)=208
2*104=208
208=208
