Answer: 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
