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 of each car for the 2-hour trip?
I have the answer as 48 mph and 56 mph. But, I am not sure how to calculate the Time / Speed / Distance.
