Question

A scuba diver is swimming in the ocean 10 feet below sea level. Then, she dives down 12 more feet to get a better look at a coral reef.What is the scuba diver's final position relative to sea level?

Answer 1

Initial position: 10 feet below sea level

Dives down: 12 more feet

Take the sea level as the 0, if the initial position is 10 ft below sea level it means -10ft relative to sea level. Then, if dives down 12 more ft subtract from -10ft the 12ft to get the final position:

`-10-12=-22`Then. the final position relative to sea level is -22 feet
