Answer:

3t-10

Step-by-step explanation:

$( \frac{12t}{8} - 5)2$

$= (\frac{12t}{8} - \frac{5 \times 8}{8} )2$

$= ( \frac{12t - 40}{8} )2$

$= ( \frac{2(12t - 8)}{8} )$

How many times would you have to run back and forth across the length of a football field to run about 1 km?

Eduardwww [97]

The length of a football field is 91 meters which is equal to 0.091 km
so to run about 1km back and forth across the length of a football team, one will run for 1/0.091= 10.98 times which approximately 11 times.

Answer:

It will take Josie 80 minutes to run 10 miles.

Step-by-step explanation:

We can set up a proportion between the number of minutes she runs to the number of miles she runs. From what we know in the equation, we know that it takes her 24 minutes to run 3 miles, and it takes x minutes to run 10 miles. We can represent this in a proportion!

We know that the ratio of 24:3 will be the same for any number of miles, so we can say

$\frac{24}{3} =\frac{x}{10\\}$
