Is this the question in its entirety?

**Quote:**

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 2-hour trip?

Two cars traveling for 2 hours apiece go 208 miles. In other words, 4 hours of total driving = 208 miles. 208/4 = 52 mph average for both cars.

If one car was going 8mph faster than the other car and we want to find out each cars average just find the two speeds that are 8mph and average at 52. In this case (52+4) and (52-4) or 56mph and 48 mph.

Double-check answer:

48(2)+56(2) = 96+112 = 208 miles
