On a math test it tooks kiera 30 minutes to do 6 problems. heath finished 18 problems in 40 minutes did the students work at the same rate

Kiera: 30 minutes / 6 problems = 5 minutes per problem.

Heath: 40 minutes / 18 problems = 2.22 minutes per problem.

The times per problem are different so they did not work at the same rate.
