Use the information below to answer the following.

A group of students investigated physics concepts at an ice-skating rink. The students skated at different speeds and pushed boxes across the ice. The boxes were exactly the same except for their mass.

MASS OF BOXES
Box Mass (kilograms)
1 45
2 60
3 70
4 85

The perimeter of the skating rink is 75 meters. A student skates the perimeter of the rink 4 times in 5 minutes.

What is the average speed of the student in meters per second?

  1. 1 meter per second
  2. 15 meters per second
