50 m. What is his elevation relative to the mean sea level at the end of the ride?​

Answer 1

Answer:

When he started, he was at an elevation of - 55 m.

During the ride, the elevation changes as 412m,-125m,272m,-343m,490m,-640m and 50m.

Add up all the measures of the elevation of the roller Coaster that are positive-55m+412m+272m+490m+50m=1279m

Now add up all the measures of the rolar costar that are negative-(-125m)+(-343m)+(-640m)= - 1108 m

Add up these two- 1279m+(-1108m)= 171m.
