Welcome to our Problem of the Week page. These free problems we’re created by Math Crush or discovered somewhere in the math world. Each page includes the question and a solution. We enjoy these types of open questions and answers because they allow students to use other prior knowledge to solve. Use them as you want, but our recommendation is to put a problem up once a week and call it the Problem of the Week. Students can solve it on their own time for extra credit or a treat. | |

AirstrikeQuestion: Four injured military men are stuck in enemy territory on one side of a bridge and have issued an airstrike which will destroy everything in the area in 17 minutes.
They need to cross the bridge to safety, but it is heavily mined and they only have one mine detector. The mines are constantly moving which makes them impossible to
mark. This means the mine detector needs to be taken back and forth so no one blows up. Of course it cannot be thrown either. In addition, the bridge is old and can
only hold two people at a time. Each man has different injuries and can walk at different speeds. When a pair crosses they must walk together at the rate of the slower man.
Clark has only scratches and bruises and will take one minute to cross. Hershel lost an arm and is very tired and will take two minute to cross. Tank lost a foot and will
take five minutes to cross. Skippy has many injuries and will take ten minutes to cross. |
