A whale is swimming at a current depth of 15 meters below the surface. It swims up toward the surface and arrives there 9.5 seconds later. Find the quotient that best describes the rate of change in the whale's depth. Give your answer to the nearest hundredth.

Answer 1

The whale starts at a depth of 15 meters and reaches the surface 9.5 seconds later. The change in depth is 15 meters (from 15 meters below the surface to being at the surface). The change in time is 9.5 seconds.

To find the rate of change in the whale's depth, we divide the change in depth by the change in time: rate of change = change in depth / change in time.

rate of change = 15 meters / 9.5 seconds ≈ 1.58 meters/second

Therefore, the rate of change in the whale's depth is approximately 1.58 meters/second.
