Step-by-step explanation:

The volume of a cube.

The formula is V = s^3 where is the the "whole side length" of the cube. The cube requires three dimensions be multiplied together to find its volume.

Kira ran 8 1/5 miles in 69 7/10 minutes. What is Kira’s average time per mile?
Setler79 [48]

Answer:

1 mile = 8.5 minutes

Step-by-step explanation:

<u>Determining the equation:</u>

Kira ran 8 1/5 miles in 69 7/10 minutes.

⇒ Kira = 8 1/5 miles = 69 7/10 minutes

⇒ 41/5 miles = 697/10 minutes

<u>Simplifying both sides:</u>

⇒ 41/5 miles = 697/10 minutes

⇒ 41 miles = 697/2 minutes

<u>Using cross multiplication:</u>

⇒ 41 × 2 miles = 697 minutes

⇒ 82 miles = 697 minutes

<u>Dividing 82 both sides:</u>

⇒ 82 miles = 697 minutes

⇒ 82/82 miles = 697/82 minutes

⇒ 1 mile = 8.5 minutes
