Answer: 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.
