You are at an evolution of 368 m above the sea level as you started to motor ride during the ride your evaluation change by following series
544 m , - 278 m, 110m , - 132 M, 488m and 90 m. what is your evaluation relative to sea level at the end of your ride.
Total depth of elevation= 368m
now, during the ride, elevation changes by the following meters 544m, -278m, 110m, -132m, 488m, 90m.
therefore,
Elevation relative to the sea level at the end of the ride =
380+[544 + (-278) + 110 + (-132) + 488 + 90]
=1202 m
