Howard is taking his kindergarten class to the museum on a school trip. He splits the class equally into 3 groups and then each of the groups goes through the museum one student at a time. If the class has 18 students in total and each student takes 4 minutes to go through the museum, then how long, in minutes, does it take each group to go through the museum?

How many students are in each group? ** As the groups are equally sized, they must each have 18 students in the class / 3 groups = <<18/3=6>>6 students in each group.
How many minutes does each group take to go through the museum? ** So each group takes 6 students in each group * 4 minutes per each student’s trip = <<6*4=24>>24 minutes to go through the museum.
