275. I divided 440 by 48 and then multiplied the answer by thirty.
An exponential decay function is a function that decreases in quantity. Hope this helps
If the students are hiking at 4 km/h, you'll need to use the schedule to find <em>the total number of hours they spent hiking</em> and multiply it by that rate. According to the activity column, how many time chunks are they hiking for, and how long does each of them last? You can use that information to help answer the question.
