A scuba diver at a depth of −12 ft (12 ft below sea level), dives down to a coral reef that is 3.5 times the diver's original depth. What is the diver's new depth?

-42 ft

Step-by-step explanation:

The diver's new depth is -42 ft.                                      

Step-by-step explanation:

Given : A scuba diver at a depth of -12 ft (12 ft below sea level), dives down to a coral reef that is 3.5 times the diver's original depth.

To find : What is the diver's new depth?

Solution :

A scuba diver at a depth of -12 ft.

Dives down to a coral reef that is 3.5 times the diver's original depth.

So, We have to multiply the original depth by 3.5.

i.e. d = -12 x 3.5

d = -42

Therefore, the diver's new depth is -42 ft.
