Final answer:
The question is about capacity calculation in Mathematics. Without additional information about Brian's specific needs, we cannot determine how many ounces he needs. Instead, we use Junior's example to show that 3 gallons for a 3-day hike is equivalent to 384 fluid ounces, applying the conversion of 1 gallon to 128 ounces.
Step-by-step explanation:
The subject of the question is Mathematics as it involves calculations related to units of capacity. To answer whether Brian needs to stop at the remote water fountain to fill his water bottles, we would need additional information that specifies Brian's need compared to what has been provided for Junior's scenario. Since there is no specific information given about Brian's situation, I cannot accurately choose an option from a) Yes, 32 ounces b) No, not needed c) Yes, 16 ounces d) No, 8 ounces. However, I can provide information on how to calculate the amount of water an individual would need for a hike based on Junior's example.
Using the conversion that 1 gallon equals 128 fluid ounces, for a 3-day hike, the calculation is as follows:
- Find the unit equivalence: 1 gallon = 128 fluid ounces.
- Multiply the number of gallons by the unit equivalence: 3 × 128 = 384.
Therefore, for a 3-day hike, the individual would need 384 fluid ounces of water. This approach can be used by anyone, including Brian, to determine the amount of water to take on a hike, considering the average person needs 1 gallon of water per day according to the survival guide.
