If i run 10 miles in 85 minutes. at the same rate how many minutes would it take to run 8 miles?

Hi there!

In order to figure this out, we'll need to set up a proportion. This is the proportion we'll use: 10/85 = 8/x. Then, we need to cross-multiply: 10x = 680. Lastly, we'll divide both sides by 10 to figure out how long it takes to run 8 miles: x = 68 minutes.

Hope this helps!! :)
If there's anything else that I can help you with, please let me know!

This law is sometimes called the grouping property. as you can see, regardless of how the numbers are grouped, the answer is still 13. the associative law of multiplication is similar to the same law for addition. it says that no matter how you group numbers you are multiplying together, you will get the same answer.
