We are given that the group will go up at a rate of 4 miles per day, thus the rate the group will come down at a rate of 4*1.5 = 6 miles per day.LUANDATO wrote:A group of hikers is planning a trip that will take them up a mountain using one route and back down using another route.

Since the group took two days to go up, they would take two days to come down.
Distance of the route while coming down = time*rate = 2 days * 6 miles/day = 12 miles.
The correct answer: D
Hope this helps!

Since the rate going downhill is 4 x 1.5 = 6 miles per day and it will also take 2 days, the downhill route is 6 x 2 = 12 miles.BTGmoderatorLU wrote:A group of hikers is planning a trip that will take them up a mountain using one route and back down using another route.
