Question

A fish was swimming 2 ½ feet below the water's surface at 1:00 pm. Three hours later, the fish was at a depth that is 3 ¼ feet below where it was at 1:00 pm. What rational number represents the position of the fist with respect to the water's surface at 4:00 pm?

Answer 1

The fish will be at a distance of 5 3/4 ft from the water surface at 4:00 pm

Explanation:

Here, we want to find a rational number that represents the position of the Fish at 4pm

Initially it was at a depth of 2 1/2 ft below the water surface

At 4pm, it went 3 1/4 ft further

Thus, its position with respect to the water surface at 4 pm will be;

2 1/2 + 3 1/4

= 5/2 + 13/4 = (10 + 13)/4 = 23/4 = 5 3/4 ft
