It is recommended that hikers drink 24 ounces of water and hour. If a canteen has 24 ounces of water how much should the amount of water in the canteen change every 10 minutes?
A. 4 ounces
B. 0.4 ounces
C. -0.4 ounces
D. -4 ounces
The recommended amount of water for hikers to drink in an hour is 24 ounces. There are 60 minutes in an hour, so the recommended amount of water for hikers to drink per minute is 24/60 = 0.4 ounces.
Since the time given is 10 minutes, the amount of water in the canteen should change by 0.4 ounces every 10 minutes.
Therefore, the answer is B. 0.4 ounces.
To figure out how much the amount of water in the canteen should change every 10 minutes, we need to determine how many 10-minute intervals are in an hour. Since there are 60 minutes in an hour, there are 6 10-minute intervals in an hour (60 minutes ÷ 10 minutes = 6 intervals).
Next, we calculate how much water should be consumed in one 10-minute interval by dividing the recommended amount of water by the number of intervals. In this case, we divide 24 ounces by 6 intervals.
24 ounces ÷ 6 intervals = 4 ounces
Therefore, the amount of water in the canteen should change by 4 ounces every 10 minutes.
Therefore, the correct answer is A. 4 ounces.
To find out how much the amount of water in the canteen should change every 10 minutes, we can divide the recommended amount of water per hour (24 ounces) by the number of 10-minute intervals in an hour (6 intervals).
24 ounces / 6 intervals = 4 ounces of water per 10 minutes
Therefore, the correct answer is A. 4 ounces. The amount of water in the canteen should change by 4 ounces every 10 minutes to maintain the recommended hydration rate for hikers.
