Question

When planning a more strenuous hike, Brett figures that he will need at least 0.5 liters of water for each hour on the trail. He also plans to always have at least 1.80 liters of water as a general reserve. If x represents the duration of the hike (in hours) and y represents the amount of water needed (in liters) for a hike, the following inequality describes this relation:

y greater or equal than 0.5 x plus 1.8

Which of the following would be a solution to this situation?

Answer 1

Answer:

Having 4.5 liters of water for 4 hours of hiking

Step-by-step explanation:

If you plug in 4.5 for y and 4 for x, you get:

4.5 greater or equal than 0.5 left parenthesis 4 right parenthesis plus 1.8

4.5 greater or equal than 2 plus 1.8

4.5 greater or equal than 3.8

This is a true statement so having 4.5 liters of water for 4 hours of hiking would be a solution.
