Question

A seal is swimming in the ocean 5 feet below sea level. It dives down 12 feet to catch some fish. Then, the seal swims 8 feet up towards the surface with its catch. What is the seal’s final elevation in relation to sea level?

Answer 1

Answer:

The seal's final elevation is 9 feet below sea level.

Step-by-step explanation:

The seal's orginal depth = 5 feet.

It dove down 12 feet to catch fish.

Therefore,

New depth = 5 + 12 feet

= 17 feet

It swam 8 feet up again.

Therefore,

Final depth = 17 - 8 feet (since it swam upwards, so we subtract)

= 9 feet.
