Question

Melanie and her cousin Grace are arguing about who is

the faster swimmer. Grace: 325 m in 5.5 min
Melanie:300 m in 5 min

Answer 1

Grace is faster.

Explanation:

To find unit rate, you divide the m by the minutes. so 325 ÷ 5.5 and 300 ÷ 5!

325 ÷ 5.5 = 59.09

and

300 ÷ 5 = 60

So Grace is faster since she took less time to do more distance!

Answer 2

Grace is the faster swimmer

Explanation:

because Grace can do 25 m in .5 min, whereas Melanie can do 65 m in 1 minute, or 32.5 m in .5 min.

equation-

300 ÷ 5 = 60

325 ÷ 5 = 65
