Question

A pilot whale is swimming at 20 feet below sea level. He dives to a depth of 3290 feet in 15 minutes. What is the change in depth per minute?

Answer 1

218 feet per minute

Explanation:

To find this, first subtract the initial amount (20) from the depth he soon reaches (3290). This will leave you with the amount of 3270 which is the distance the pilot whale went.

To find the feet per minute, divide by new depth by 15 in order to get the final answer of 218 feet per minute.

Hope this helps!
