Tough and Tricky questions: Word Problems.
If a certain factory makes a total of 30,720 wrenches, how many minutes does the factory take to make the wrenches?
(1) The factory creates the wrenches without interruption at a rate of 32 wrenches per second.
(2) It takes 4 times as long for the factory to create the wrenches as it does to load them into trucks, and it takes the factory a total of 20 minutes to do both.
Kudos for a correct solution.
