An hiking group wanted to travel a long chapter of the Appalachian Trail for 4 days. They planned to hike 6 hours per day and wanted to complete a trail chapter that was 60 miles long. what rate of speed would they have to average to complete the trail chapter as planned?
to complete the 60 miles in a single 6-hour day, they'd have to average 60/6 = 10 mph.
So, to make kit 4 days, they'd have to average 10/4 = 2.5 mph.
