Question

A scuba diver dives 80 feet below the surface. After a while, the diver rises 3 feet per

minute. Which integer describes the position if the diver in relation to the surface of
the water 8 minutes after beginning to rise?
A. -56
B. -66
C. -72
D. -88

Answer 1

The position of the diver in relation to the surface of the water 8 minutes after beginning to rise can be calculated as follows:

The diver was at a depth of 80 feet below the surface initially. After 8 minutes of rising, the diver has come up to the surface by 3 x 8 = 24 feet. So, the diver's position in relation to the surface of the water is:

80 - 24 = 56 feet below the surface.

Therefore, the integer that describes the position of the diver in relation to the surface of the water 8 minutes after beginning to rise is A. -56.
