## Actual Distance Formula

The following formula is used to calculate the Actual Distance.

AD = MD / (1/X)

- Where AD is the Actual Distance
- X is the map scale (1:X)
- MD is the measured distance

To calculate the actual distance, divide the map scale by the measured distance.

## How to Calculate Actual Distance?

The following example problems outline how to calculate Actual Distance.

Example Problem #1:

- First, determine the map scale (1:X).
- The map scale (1:X) is given as: 50,000.

- Next, determine the measured distance.
- The measured distance is provided as: 3.

- Finally, calculate the Actual Distance using the equation above:

AD = MD / (1/X)

The values given above are inserted into the equation below and the solution is calculated:

AD = 3 / (1/50,000) = 150,000

Example Problem #2:** **

For this problem, the variables needed are provided below:

map scale (1:X) = 2,500

measured distance = 10

This example problem is a test of your knowledge on the subject. Use the calculator above to check your answer.

AD = MD / (1/X)** = ?**
