Question

The depth of Lake Carl is about 1 1/8 miles. Lake Susan is 3 times as deep as Lake Carl. Lake Wayne is 2 times as deep as Lake Susan. How much deeper is Lake Wayne than Lake Susan?

Answer 1

Answer:

$3\frac{3}{8}$

Step-by-step explanation:

Let LC be Lake Carl, LS be Lake Susan, and LW be Lake Wayne

First, find a way to denote all the lakes using one lake depth

LC = 1 1/8

LS = 3LC

LW = 3LS or 6LC

Then write an equation.

LW - LS = 6LC - 3LC = 3LC

Substitute LC and calculate.

3 * 1 1/8 = 3 3/8

Hope this helps :)

Have a great day!
