Hank the hiker would like to go on a hike. He only has four hours available today for the hike. The expression below we be used 1/2 miles given + 1/2 given elevation/1000 and add the two together to get Total Hours needed

1/2d + 1/2e where d=miles; e = elevation/ 1000 feet

This is a general guide to determine how much time, in hours, a hiker should allow for hiking a trail with a distance of d miles and given elevation increase. The elevation is divided by 1,000 feet which will provide the amount of time in hours due to elevation. The trail Hank would like to hike is 6 miles long and has an elevation gain of 3000 ft. Will Hank be able to complete this hike in the block of time he has available today?
