Math Problem of the Week - Upper Elementary - May 23, 2021 to May 29, 2021

Upper Elementary: 

Question: Eight groups of children are performing skits at their summer camp comedy show. Each skit is 5 minutes long. If each group performs once and the campers must be done with the comedy show by 9:15 PM, then what is the latest time they can start the show?

Answer: 8:35 PM

Solution: The amount of time is takes for all of the groups to finish their skits is 8 x 5 = 40 minutes. Since they have to finish the show by 9:15 PM, we count back 40 minutes before 9:15 PM to 8:35 PM.
