When planning a more strenuous hike, Natalie figures that she will need at least 0.6 liters of water for each hour on the trail. She also plans to always have at least 1.25 liters of water as a general reserve. Let represent the duration of the hike (in hours) and let represent the amount of water needed (in liters) for a hike. Which inequality describes the relation between and ?

Solution

Let t be duration in hour
them amount of water required,
w(t) = 1.25 + 0.6*t

I have added 1.25 as at time t= 0 , amount of water required =1.25. It needs to be reserved
