Question

The costa Family hiked a trial that was two miles in one direction How many feet was the hike round trip?

Answer 1

Since the costa family hiked two miles in one direction. You have multiply 2+2 to find the round trip. You get 4, but that isn't the answer because it is in miles not feet. You have to multiply 4 x 5280, because there are 5280 feet in one mile.  You get 21120 feet. Hope this helps. :-)
