Tricky math question, please help! Very curious of the answer but I suck at math.

If he needs to take 40, and wants to spread them out, it's pretty easy. Let's assume one at the start. So he has 39 left. If he has 2160 miles to take another 39 photo's they have to be evenly apart.

Trip length / number of photos = how often

2160 / 39 = 55.4miles. So every 55-56miles he should stop for a photo and his last shot will be at the end.

** I think you are all forgetting he needs one at the start, so every 54 miles while almost true, neglects a starting photo as the first photo then starts 54 miles into the trip **

Ok well first take how many feet in a mile: 5280, then multiply that by 2160 to get how many feet in the appalachian trail. Then divide that answer by 40 to get: 285,120

so your friend should take one picture every 285,120 feet.

also known as 86.9 kilometers, or 54 miles

Hope this helps!!!!!!!

54.7 Miles

54...54...54

One every 54 miles

2160/40 = 54

wow lol..
2160/40 = 54
So every 54 miles he takes one.
