Math CentralQuandaries & Queries


Question from jazzy:

ann and tim saw two movies in one day.The two movies lasted 4hours long .One movie was an half hour longer than the other .How many hours did the shorter movie run


If the two movies were the same length they would be 2 hours each. If one movie was 5 minutes longer and the other were 5 minutes shorter the total time would still be 2 hours and the difference in lengths of the movies would be 10 minutes.

I hope this helps,
