Question 100077
the first car has a 22.5mi head start -- 45mph*.5h=22.5mi


the second car goes 10mph faster so it will take 2.25h to catch up -- 22.5mi/10 mph=2.25h


at this point, the first car has been driving 2.75h


since it takes 3h to get to the game (135mi/45mph), the second car catches up before the first car arrives
