Question

A scuba diver descended to a depth of -22 meters (or 22 meters below sea level). The ocean floor is at a depth of -71 meters. How much farther would she need to descend to reach the ocean floor?

Answer 1

The answer is: she would need to descend 49 more meters to reach the ocean floor.

Explanation:

All you have to do to find the answer is subtract the number of meters she already dived from the number of meters the ocean floor is from the surface of the water. This makes the equation 71 - 22 = ? which equals 49. So she would need to descend 49 more meters to reach the ocean floor.
