Problema Solution
Students get to switch classes every 20 minutes. The students are in school for 7 hours. If a student switched as much as possible, how many times would that student get to visit another classroom?
Answer provided by our tutors
first lets find how many minutes are in 7 hour:
1 hour = 60 min
7 hours = 7*60 = 420 min
the maximum number of switches will happen if the student is switching every 20 min
divide the total time by 20 (the minimum time between 2 switches):
420 : 20 = 21
the student gets to visit another classroom 21 times.
