You are at an elevation 380m above the sea level as you start a motor ride. During the ride, your elevation changes by the following meters 540m, -286m, 116m, -152m, 490m, -844m, 94m. what is your elevation relative to the sea level at the end of the ride?
Total depth of elevation= 380m
now, during the ride, elevation changes by the following meters 540m, -286m, 116m, -152m, 490m, -844m, 94m.
therefore,
Elevation relative to the sea level at the end of the ride = 380+[540+(-286)+116+(-152)+490+(-844)+94]=338m
