Question

16. 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 meters: 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

Answer:

To get final elevation we have to add all the elevations in original elevation.

So, elevation relative to the sea level at the end of the ride

=[380+540+(−268)+116+(−152)+490+(−844)+94] m=[380+540−268+116−152+490−844+94] m=[380+540+116+490+94−268−152−844] m=[1620−1264]m=356 m

So, elevation at the end of ride will be 356 m.

Answer 2

Final altitude

= Sum of the changes in altitudes

= 380 m + 540 m + (-268 m) + 116 m + (-152 m) + 490 m + (-844 m) + 94 m

= 380 m + 540 m - 268 m + 116 m - 152 m + 490 m - 844 m + 94 m

= 356 m ( above sea level)

Therefore, the final altitude at the end of the motor ride is 356 m above sea level.
