Question

Mia ran 10 laps in 6 minutes. Shawna ran 5 laps in 4 minutes.

Which person ran at a faster rate? Use mathematics to justify your answer.

Answer 1

Mia is faster because if we take 5/4 we will need to get the the minutes to the same so they could both go into 12 minutes. So Mia would run 20 laps in 12 minutes and Shawna would run 15 laps in 12 minutes

Answer 2

mia

Explanation:

mia: 10/6 per minute

shawn: 5/4 per minute

common denominator is 12, multiply by 2 and 3

20/12 lap per minute mia

15/12 laps per minute shawn

20 > 15
