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 the the other car, what was the average speed for each car for the 2-hour trip?
-------------------------------------------
1st car DATA:
Rate = x mph ; time = 2 hr. ; distance = 2x miles
--------------------------------------------
2nd car DATA:
Rate = x+8 mph ; time = 2 hr. ; distance = 2(x+8) miles
--------------------------------------------
EQUATION:
distance + distance = 208 miles
2x + 2(x+8) = 208
x + x+8 = 104
2x =96
x = 48 mph (1st car)
x+8 = 56 mph (2nd car)
