Question

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

Elevation relative to the sea level at the end of the ride

= [380 + 540 – 268 + 116 – 152 + 490 – 844 + 94] m

= [380 + 540 + 116 + 490 + 94 – 268 – 152 – 844] m

= [1620 – 1264] m

= 356 m
