Question

A navy submarine descended at a rate of 4 feet per second. a. Write the descent rate as an integer. b. Write an expression to find the submarine's elevation after 5 minutes.

Answer 1

1200

Explanation:

Since the value they are asking for is in minutes, we need to convert seconds to minutes. We can do that by multiplying 4 and 60, because there are 60 seconds in a minute, and we need to find the value of one minute. Also because the value they gave is 4. When we do this, we get 240. To get the final answer, we need to multiply 240 and 5, because 240 is the descending rate per minute, and they are asking for 5 minutes. When we do this, we get 1200.

(I might get this wrong, so like yeah.)
