Answer:

190 ft deep

Explanation:

What the problem doesn't tell you is that "this situation" is the height of the ball relative to the ground level Lisa is standing on. The ball is dropped from a height of 6 feet above that level. The variable 'h' is said to represent the drop height (in feet), so h = 6. Evaluating the expression for t=3.5 will tell the height of the ball relative to ground level after 3.5 seconds.

-16(3.5)² +6 = -196 +6 = -190

The bottom of the well is 190 feet below ground level.
