Ryan was preparing for a big adventure. He was packing his gear for a trek to the top of Mt. McKinley. At 20,320 feet, Mount McKinley is the highest mountain on the North American continent. It will be a long and difficult climb, but Ryan is ready for the challenge.
He will begin the climb from a base camp at 6,000 feet and plans to increase his elevation about half a mile per day. To the nearest half a day, how long will it take Ryan to reach the top of Mount McKinley?
