Answer 1

The lake is 11.3 m below sea level.

Explanation:

Mei's initial position on the field was 0.5 m below sea level.

The lantern rises 913.9 m after its release.

The lantern descends 925.2 m to land on the surface of a lake.

Let the elevation of the lake to sea level be represented by x.

So that;

x = 913.9 - 925.2

= -11.3

x = 11.3 m below sea level.

Therefore, the lake is 11.3 m below sea level.
