To determine the total amount of water Victor should drink for all three hikes, you first need to find the total distance he will hike and then multiply that distance by the amount of water he needs per mile.
The distances of the trails are as follows:
- Half Dome trail: 16 miles
- Mirror Lake trail: 5 miles
- Snow Creek trail: 9 miles
Now, add the distances together:
\[ 16 \text{ miles} + 5 \text{ miles} + 9 \text{ miles} = 30 \text{ miles} \]
According to the article, Victor should drink 12 fluid ounces of water for each mile hiked. Therefore, to find the total amount of water to drink, multiply the total miles by 12 fluid ounces:
\[ 30 \text{ miles} \times 12 \text{ fluid ounces per mile} = 360 \text{ fluid ounces} \]
Thus, Victor should drink 360 fluid ounces of water in total over the course of all three hikes.
