Cedar Falls Middle School has students in grades 4 – 7 and each year they are challenged to earn as many Accelerated Reader points as they can. The 10 students in each grade with the most points get to try an escape room set up by the teachers. Only 8 students can try the escape room at a time. They have 45 minutes to try and escape. If every group uses their full 45 minutes, how long will it take for everyone to try the escape room?

How many students are in each grade? ** There are 4 grades in the middle school x 10 students = <<4*10=40>>40 students who get to try the escape room.
How many groups will try the escape room? ** There will be 40 students / 8 students in a group = <<40/8=5>>5 groups who get to try the escape room.
How long will it take for everyone to try the escape room? ** It will take 5 groups x 45 minutes = <<5*45=225>>225 minutes.
