Question 627818: PLEASE HELP ME SOLVE THIS PROBLEM. THANK YOU.
MOTION PROBLEMS:
1. A ship leaves a dock moving at 24mi/h. Three hours later a second ship sets out from the same dock at 32mi/h. How long will it take for the second ship to overtake the first?
2. Two cars 210km apart met each other in 2hrs. If one car traveled at 60km/h, then at what rate did the second car travel?

During the 3 hour head start, the first ship travels 3 X 24 = 72 miles. The second ship is traveling 8 mph faster, so how long to cover 72 miles at 8 mph?
