Final answer:
The vertical distance between the kite and the fish is 25 m.
Step-by-step explanation:
To find the vertical distance between the kite and the fish, we need to calculate the difference in their heights. The kite is flying at a height of 20 m above the ground, while the fish is at a depth of 5 m underwater. The height of the kite is positive since it is above the ground, while the depth of the fish is negative since it is below the surface. Therefore, the vertical distance between them is:
Vertical Distance = Height of the kite - Depth of the fish
Vertical Distance = 20 m - (-5 m) = 20 m + 5 m = 25 m
So, the vertical distance between the kite and the fish is 25 m.
