The Depth of the Scientist before dropping is; 42.2 ft
<h3>How to calculate sea level elevation?</h3>
It is pertinent to note that sea level is usually considered zero level. Thus, one is either above the sea level (positive sign) or below the sea level.
Now, we are told that the scientist was already below the sea level before she dropped 24.9 ft.
Now, if after dropping 24.9 ft, she is now 66.7 ft below sea level, then it means that the depth she was at before dropping 24.9 ft is;
Depth before dropping 24.9 ft = 66.7 - 24.9
Depth before dropping = 42.2 ft

9.81 times 10 to the -5th power
If you mean 756.04, the answer is 756.0. 4 is closer to 0.
