darrin hiked the shortest route from the trailhead to hart moutin in 73.4 hours. what is the avarage number of miles he hiked in 1 hour?

How many miles is it from Trailhead to Hart Mountain?

10 in 5 7ths

Do you mean 10 5/7 miles?

yes that's what i mean

This must be a snail doing the hiking.
10.71 divided by 73.4 = 0.146 miles per hour. That's a little longer than a football field.
Are you using a map scale? 
yes im using a map that tells how many miles to get to the places!

I bet that you measured on your map and found that it was 10 5/7 inches from one place to another. Now use your map scale to find out how far that would be in actual miles.
Check this site.

i know the ansewer is 2 2/3 i just don't know how to work it out.

If Darrin averaged 2 2/3 miles per hour on a 73.4 hour long hike, then the distance must be about 31.5 miles. Check your distance again.
