Darla sees a duck and a fish at a pond. The duck is 2 1/2 feet above the surface of the pond. The fish is 1 3/8 feet below the surface of the pond. What is the distance, in feet, between the duck and the fish? 1 1/3 1 1/8 3 7/8 3 4/10

3 7/8 feet

Step-by-step explanation:

From the question, we are informed that Darla sees a duck and a fish at a pond and that the duck is 2 1/2 feet above the surface of the pond while the fish is 1 3/8 feet below the surface of the pond.

The distance, in feet, between the duck and the fish will be calculated as:

= 2 1/2 - (-1 3/8)

= 2 1/2 + 1 3/8

= 2 4/8 + 1 3/8

= 3 7/8 feet

The distance, in feet, between the duck and the fish is 3 7/8 feet

-2 is the right
