Question

A submarine descended 32 feet below the surface of the ocean. It then rolls 15 feet to look at a shark. Write an expression to find its current depth. a) 32 - 15 b) 32 + 15 c) 32 * 15 d) 32 / 15

Answer 1

Explanation:

To find the submarine's current depth after descending 32 feet below the surface and then rolling 15 feet to look at a shark, you should use the subtraction operation because it descended and then rolled up, so it's subtracting the 15 feet from the initial depth.

So the expression is: 32 - 15.

The correct answer is: a) 32 - 15.
