Olivia-2.25

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

Answer 2

Answer:

Code: Olivia-2.40

Step-by-step explanation:

Given that:

Maggie runs 1/4 of a mile in 1.3 minutes

1/4 can also be written as 0.25

Speed = $\frac{Distance}{Time}$

Speed = $\frac{0.25}{1.3}$

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 = $\frac{\frac{2}{3}}{2.9}=\frac{2}{2.9*3}$

Speed = $\frac{2}{8.7}$

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
