It is recommended that hikers drink 24 ounces of water an hour. If a canteen has 24 ounces of water, how much should the amount of water in the canteen change every 10 minutes?

-4 ounces
4 ounces
-0.4 ounces
0.4 ounces

The amount of water in the canteen should decrease by 0.4 ounces every 10 minutes.

To determine how much the amount of water in the canteen should change every 10 minutes, we need to calculate the amount of water a hiker should consume in 10 minutes.

Given that hikers are recommended to drink 24 ounces of water per hour, we can calculate the amount of water to be consumed in 10 minutes:

24 ounces per hour / 60 minutes per hour = 0.4 ounces per minute.

Therefore, the amount of water in the canteen should change by 0.4 ounces every 10 minutes.

To determine how much the amount of water in the canteen should change every 10 minutes, we can use the information that hikers are recommended to drink 24 ounces of water per hour.

First, we need to convert the recommended hourly intake to the amount of water hikers should drink in 10 minutes. Since there are 60 minutes in an hour, we divide the recommended amount of water by 6 (60 minutes divided by 10 minutes).

24 ounces / 6 = 4 ounces

Therefore, the amount of water in the canteen should change by 4 ounces every 10 minutes. So the correct answer is 4 ounces.
