Using Polya's Four-Step Problem Solving Strategy, solve this: Indiana Jones needs to cross a flimsy rope bridge over a mile-long gorge. It is so dark that it is impossible to cross the bridge without a flashlight. Furthermore, the bridge is so weak that it can only support the weight of two people. The party has just one flashlight, which has a weak beam, so whenever two people cross, they are constrained to walk together, at the speed of the slower person. Indiana Jones can cross the bridge in five minutes. His girlfriend can cross in 10 minutes. His father needs 20 minutes, and his father's sidekick needs 25 minutes. They need to get everyone across safely in one hour to escape the bad guys. Can they do it?
