Answer 1

Olivia-2.25

If you would like me to explain why, please let me know.

Answer 2

Code: Olivia-2.40

Explanation:

Given that:

Maggie runs 1/4 of a mile in 1.3 minutes

1/4 can also be written as 0.25

Speed =
`(Distance)/(Time)`

Speed =
`(0.25)/(1.3)`

Speed of Maggie = 0.19 miles per minute

Speed of Maggie per hour = 0.19*60 = 11.40 miles per hour

Olivia runs 2/3 of a mile in 2.9 minutes

Speed =
`((2)/(3))/(2.9)=(2)/(2.9*3)`

Speed =
`(2)/(8.7)`

Speed of Olivia = 0.23 miles per minute

Speed of Olivia per hour = 0.23*60 = 13.80 miles per hour

Therefore,

Olivia runs faster.

Difference = 13.80 - 11.40 = 2.40 miles

Hence,

Code: Olivia-2.40
