Four people need to cross a rickety rope bridge to get back to their camp at night. Unfortunately, they only have one flashlight and it only has enough battery left for seventeen minutes of light. The bridge is too dangerous to cross without a flashlight, and itโs only strong enough to support two people at any given time. Each of the campers walks at a different speed. One can cross the bridge in 1 minute, another in 2 minutes, the third in 5 minutes, and the slow poke takes 10 minutes to cross. How do the campers make it across in 17 minutes?

Answer:1) First 1 and 2 will cross the bridge in 2 mins.(2 has been counted once)
2) 1 will come back in 1 mins total = 3 mins. ( 1 has been counted once)
3) 5 and 10 will cross the bridge in 10 mins total = 13 mins (10 has been counted once)
4) 2 will go back in 2 mins total = 15 mins(2 has been counted twice)
5) 2 will bring back 1 in 2 mins total = 17 mins( 2 has been counted thrice)
