<PRE><B>Question 217867</B>
A motorcycle traveling at 70 miles per hour overtakes a car traveling at 40 miles per hour that had a three- hour head start. How far from the starting point are the two vechicles. 
----------------------
The car is 120 miles away when the motorcycle starts.
The bike gains on the car at 30 mph (70-40).
It take 4 hours for the bike to close the gap (120/30).
In 4 hours, the bike and the car are 280 miles from the starting point.
---------
4*70 = 280
7*40 = 280
