erica [24]

Answer:

The answer is 5,030 feet.

Step-by-step explanation:

It is stated that his starting point is at an elevation of 0 feet. He climbs 3.200 feet on the first day and then adds another 1.830 feet on the second day. This makes his total elevation 3,200 + 1,830 = 5.030 feet.

As he reaches the other side of the island on the 3rd day which is at an elevation of 0 feet as well, he loses all the elevation he gained on days 1 and 2, which is 5,030 feet.

I hope this answer helps.
