A fish was swimming 3 in a half feet below the water surface at 7:00 a. M. Four hours later, the fish as at a depth that is 5 one fourth feet below where it was at 7:00 a. M. What rational number represents the position of the fish with respectto water surface at 11:00 a. M

8 3/4 below sea level

Step-by-step explanation:

Given that:

Depth of fish at 7:00 A. M = 3 1/2 feets below sea level

Depth at 11:00a.m (4 hours later) = 5 1/4 feets below it's position at 7:00 a. M

Rational number to represent position of fish with respect to the water surface at 11:00 a. M

Position at 11:00 a. M :

Addition of the two depth distances given :

(3 1/2 + 5 1/4)

7/2 + 21/4 = (14 + 21) / 4 = 35 / 4

35/4 = 8 3/4 feets below sea level
