Mary's Rock is a mountain that is popular for hiking. There is a 3.8-mile trail from the base of the mountain to the top. Elizabeth is a beginner hiker climbing the mountain for the first time. Suppose h represents the number of miles Elizabeth has hiked since starting to climb the mountain. a. Explain what the expression 3.8 - h represents. Alexis is an experienced hiker who climbed the mountain early in the morning and is already at the peak. Alexis hikes 1.8 times as fast as Elizabeth. At 10:00 am Elizabeth and Alexis start hiking towards each other. Alexis was descending while Elizabeth was ascending. For simplicity we are assuming both hikers' hike at constant speed. b. Explain what the expression 1.8h represents. c. What expression represents the cumulative distance hiked by Elizabeth and Alexis including Alexis's hike up the mountain earlier that morning.
