Question

On a math test it took Kiera 30 minutes to do 6 problems. Heath finish 18 problems in 40 minutes. Did the students work at the same rate? Explain your reasoning

Answer 1

no they did not, to have been working at the same rate it should have taken Heath 90 minutes to complete 18 problems, as 6x3 is 18, you would also multiply the time completed by 3, hope this helps

Answer 2

Kiera : 30/6 = 5 minutes per problem
Heath : 40/18 = 2.22 minutes per problem

They did not work at the same rate....Heath worked faster
