Sally was getting ready to go on a hiking trip with friends across part of the Appalachian Trail. They were trying to determine how much of the 2,200-mile trail they could cover in 7 days. They plan to walk 6 hours a day on each of the 7 days of the trip. At the rate of 5 miles every 1.5 hours, how far will they walk in 42 hours?

They'll walk 140.28 miles in 42 hours at that pace.

Step-by-step explanation:

In order to find the distance they can travel at a steady pace, we need to take the pace in wich they intend to travel and multiply it by the time that they intend to travel. In this case their pace is 5 miles every 1.5 hours it means that their pace is 5/1.5 = 3.34 m/h, if they travel for 42 hours they'll travel a distance of:

distance = 3.34*42 = 140.28 miles
