Aime hiked for 3 days across an island. He started at the shoreline, which is at an elevation of 0 feet. At the end of day 1, Jaime had gained 2,150 feet in elevation. At the end of day 2, he had gained an additional 1,970 feet in elevation. On day 3, Jaime hiked down to the shoreline on the other side of the island, which is also at an elevation of 0 feet. How many feet in elevation did he lose on day 3?

4120 feets

Step-by-step explanation:

Given that:

Starting elevation = 0 feets

Elevation gained on first day = 2150 feets

Total elevation at the end of day 1 = 0 + 2150 = 2150 feets

Elevation gained on second day = 1970 feets

Total elevation at the end of day 2 = 2150 + 1970 = 4120 feets

Elevation at the end of 3 rd day = 0 feets

Hence, elevation lost on day 3 ;

(4120 - 0) = 4120 feets
