Sample Problem

Thomas started grilling 50 hamburgers at 12:40 and finished the job at 15:10. If he spent an equal amount of time on grilling each hamburger, how long did he spend to grill each hamburger?

  min

Solution

Start time: 12:40

End time: 15:10

Elapsed time: 15:10 - 12:40 = 2 h 30 min

Time spent on grill each hamburger: 2 h 30 min ÷ 50 = 3 min

So the answer is 3 min.
