A runner can run 5 miles in 26 minutes at this rate how many miles can he run and 41.6 minutes?

diamong [38]

Answer:

8 miles

Step-by-step explanation:

Given: A runner can run 5 miles in 26 minutes, 41.6 minutes = ___

To find: At this rate, how many miles can he run and 41.6 minutes?

Solution: If the runner ran 5 miles in 26 minutes, to find how far he ran in 41.6 minutes, set up a fraction:

let x be the variable

$\frac{26}{5} = \frac{41.6}{x}$

Apply fraction cross multiply;

$26x=5\cdot \:41.6$

$26x = 208$

Divide both sides by 26

$\frac{26x}{26}=\frac{208}{26}$

Simplify

$x = 8$

Then, at the rate, the runner ran 8 miles 41.6 minutes
