a motorcycle traveling at 70 mph pvertakes a car traveling at 40 mph that had a 3 hour head start...how far from the starting point are the two vehicles?

A 3 hour lead at 40 mph --> 120 miles
The motorcycle gains on the car at 30 mph (70-40)
120 miles/30 mph = 4 hours to overtake the car
4 hr @ 70 mph = 280 miles from the starting point.
