Agroup of four people has to cross a bridge. it is dark, and they have to light the path with a flashlight. no more than two people can cross the bridge simultaneously, and the group has only one flashlight. it takes different time for the people in the group to cross the bridge

The group goes by twos with the flashlight and one of them comes back.

Step-by-step explanation:

Chris and Tracy cross with flashlight

Chris returns with flashlight

Ashley and Jalen cross with flashlight

Tracy returns with flashlight

Chris and Tracy cross with flashlight

Time altogether: 17 minutes

Because the bridge is so worn and weathered, only two people can cross at once. Because it is pitch dark out with no moon to light your way, one person must come back across the bridge with the flashlight after they have crossed to allow anyone else to cross.
