Question 1021612
If they travel in the opposite direction (the only way this problem really makes sense at this level), then in two hours they cover 208 miles.  Thus, their rates are a combined 104 miles per hour.
Call the slower car's rate, r.
The faster will be r+8.
Then we have
r + r+8 = 104
2r + 8 = 104
2r = 96
r = 48 mph (slower car)
r+8 = 56 mph (faster car)
