Two students move through each line per minute.
There are 5 lines and 600 students moved through them in 1 hour. Find out how many students go through each line in that hour:
= Number of students / Number of lines
= 600 / 5
= 120 students per line per hour
If 120 students move in each line every hour, and an hour is equivalent to 60 minutes, the number of student moving per minute is:
= Number of students / Number of minutes in an hour
= 120 students / 60 minutes
= 2 students per minute
There are therefore 2 students moving in every line per minute.
