Question

Javier jogs 3/4 of a mile in 8/1/2 minutes.

If he keeps the same pace, how many minutes will it take him to jog 1 mile?

Answer 1

11 1/3 minutes per mile.

Explanation:

3/4 miles jogged in 8 1/2 minutes.

So 1 mile jogged in: 8 1/2 divided by 3/4 = 8 1/2 x 4/3 = (17 x 4) / (2 x 3) = 11 1/3 minutes per mile

Answer 2

x = 11 1/3 minutes

Explanation:

We can write a ratio to solve

3/4 mile 1 mile

----------------- = --------------

8 1/2 minutes x minutes

Using cross products

3/4 *x = 8 1/2

Multiply each side by 4/3

4/3 * 3/4x = 8 1/2 * 4/3

x = 17/2 * 4/3

x = 34/3

x = 11 1/3
