Question

The school student council sponsored a Switch Day where students were able to switch classes every 20 minutes. The students are in school for 7 hours. If a student switched as often as possible, how many classrooms in all did that student visit? (Hint there are 60 minutes in 1 hour)

Answer 1

If the students are in school for 7 hours and are able to switch classes every 20 minutes, you can calculate how many classrooms in all can the students visit.

7 hours = 7 * 60 minutes = 420 minutes

420 minutes / 20 minutes = 21 classrooms

Result: The students can visit 21 classrooms.
