. A bird flying at a height of 750m above the level of a lake looks at a fish in the lake which is 80m below the level of the lake. What is the vertical distance between bird and fish?

To find the vertical distance between the bird and the fish, we need to consider their respective heights above and below the lake's surface. The bird is flying at a height of 750 meters above the lake, while the fish is located 80 meters below the lake's surface. To determine the total vertical distance between them, we can simply add these two distances together.

Calculating the Vertical Distance

Let's break down the calculation step by step:

• The height of the bird above the lake: 750 meters
• The depth of the fish below the lake: 80 meters

To find the total vertical distance, we add the height of the bird to the depth of the fish:

Vertical Distance = Height of Bird + Depth of Fish

Substituting the values we have:

Vertical Distance = 750 meters + 80 meters

This gives us:

Vertical Distance = 830 meters

Understanding the Result

This means that the bird is 830 meters directly above the fish. To visualize this, you can think of it like standing on a tall building while looking down into a deep hole. The height of the building represents the bird's altitude, and the depth of the hole represents how far below the surface the fish is swimming. The total distance from the top of the building to the bottom of the hole is the sum of both heights.

Real-World Application

Such calculations can be useful in various fields, including biology, environmental science, and even aviation. For instance, understanding the vertical distances in ecosystems can help scientists study predator-prey relationships, while pilots might need to know their altitude in relation to various geographical features.

In summary, the vertical distance between the bird and the fish is 830 meters, which illustrates how we can use simple addition to solve problems involving heights and depths in a straightforward manner.
