Windshield Wipers
A car is driving on the Thruway through a rainstorm. A truck is also driving on the Thruway in the same direction during the same rainstorm. Both the car and the truck have their windshield wipers going on the highest settings. The truck’s wiper has a 2 foot blade that attaches to the wiper arm at one end and the arm measures 10 inches. The car’s wiper blade is 23 inches long. This blade also attaches to the wiper arm at one end and measures 10 inches. If the truck’s wiper lies flat when turned off and forms a 90o angle when fully functioning and the car’s wiper also lies flat when turned off and forms a 120o angle when fully functioning, which vehicle will be able to see better when the wipers clean the windshields?
