Answer:

See Explanation

Step-by-step explanation:

The options are not given; However, the following explanation can guide you;

Represent the smaller fish with y and the bigger fish with x such that

$y = 13\ feet$

$x = 4\ feet$

The distance between them can be calculated using any of the following;

1.

$Distance = y - x$

This gives:

$Distance = 13 - 4$

$Distance = 9\ feet$

2.

$Distance = |y - x|$

$Distance = |13 - 4|$

$Distance = |9|$

$Distance = 9\ feet$

3.

$Distance = |x - y|$

$Distance = |4 - 13|$

$Distance = |-9|$

$Distance = 9\ feet$
