,Maura run faster.

Step-by-step explanation:

Given  : Maura runs 5 miles in 1.25 hours. Ava runs 3 miles in 50 minutes, or 0.83 hour.

To find : Who runs faster.

Solution : We have given

Maura runs in 1.25 hours = 5 miles.

Maura runs in 1 hours =   miles.

Maura runs in 1 hours =   miles.

                                    = 4 miles.

Ava runs in 0.83 hour=  3 miles.

Ava runs in  1 hour=  3 * 0.83 miles.

                               = 2.49 miles.

So, Maura run faster.

Therefore,Maura run faster.

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
