Question

The position of a diving bell is −34−34 mile relative to sea level. the diving bell reached this position after dropping from sea level at a constant rate for 112112 hours. what was the position of the diving bell relative to sea level 1 hour after it began its descent? enter your answer in simplest form in the box.

Answer 1

since it travel at a constant speed. Calculate first its speed of descent.

S = -3/4 mile / 1 ½ hr

S = -0.5 mile an hour

So the position of the diving bell relative to sea level 1 hour after it began its descent is

D = (0.5 mile/ hr) x 1 hr = - 0.5 mile
