Question 123

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 1

Given the initial position of the motor was 380 m.
During the ride, change in elevation was 540 m, -268 m, 116 m, -152 m, 490 m, -844 m, and 94 m
Net change in position = 540 + (-268) + (116) + (-152) + (490) + (-844) + 94 = -24 m
Initial position was 380 m. So, at the end of the ride the position would be = 380 + (- 24) = 356 m
