You are at an elevation 380 m above sea level as you start a motor ride. During the ride, your elevation changes by the following metres: 540 m, –268 m, 116 m, –152 m, 490 m, –844 m, 94 m. What is your elevation relative to the sea level at the end of the ride?

Answer :

Given that, starting point during the motor ride = 380 m

The changes in the elevation during the ride are given to be 540 m, -268 m, 116 m, -152 m, 490 m, -844 m and 94 m.


The changes in the elevation can be calculated as :


Changes = 540 + (-268) + 116 + (-152) + (490) + (-844) + 94


Changes = 540 – 268 + 116 – 152 + 490 – 844 + 94


Changes = -24 m


To find elevation at the end of the ride is found by,


Elevation = (Elevation at the starting point) + (Changes in elevation)


Elevation = 380 + (-24)


Elevation = 356 m


Thus, elevation at the end of the ride is 356 m.
