Jim stands on a dock that is 3 3/4 feet above the lake. He dives down 12 1/2 feet below the dock. What is Jims vertical location relative to the lake surface?

Given:

Jim stands on a dock that is feet above the lake. He dives down feet below the dock.

To find:

The Jims vertical location relative to the lake surface.

Solution:

We have,

Vertical location of dock relative to the lake surface feet

He dives down feet below the dock. So,

Vertical location relative to the lake surface

Taking LCM, we get

Here, negative sign means Jim location is below the lake surface.

Therefore, Jim is feet below the lake surface.
