If they will go up the mountain at a rate of 4 miles per day and it will take them two days, how many miles long is the route down the mountain?

D = S*T
Given condition is for UP the mountain hikers takes 4 miles per day and total 2 days... miles = 8 miles...
For DOWN speed they take = 3/2(4) = 6 miles per day and for the same 2 days... miles = 12 miles..
IMO option D is correct answer..
OA please..will correct if I missed anything..

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.
Answer: D
