Use reasoning to answer the following question.
Selena and Josh were running in a race. Together they ran 36 miles. Josh ran half of the distance that Selena ran. How many miles did Selena run?

24
Let J = Josh's distance.

2J = Selena's distance.

J + 2J = 36.

3J = 36 miles.

J = 12.

2J = 24 miles.

Selena ran 24 miles.

The answer is 24
