Oct 13, 2025 by windailys.com 8 views

When it comes to creating a map, understanding the scale and the relationship between different locations is crucial. In this scenario, we have three towns: A, B, and C. Town A is 2km due north of town B, and town C is 5km east of town A. We are tasked with creating a map with a scale of 1:25000 and determining the distance between town A and town B on the map.

The Scale of the Map

The scale of the map is 1:25000, which means that 1 unit on the map represents 25000 units in real life. This scale is commonly used for topographic maps and is suitable for showing detailed features of the landscape.

Converting Real-World Distances to Map Distances

To determine the distance between town A and town B on the map, we need to convert the real-world distance between the two towns to a map distance. Since town A is 2km due north of town B, we can use the scale of the map to convert this distance to a map distance.

Calculating the Map Distance

Using the scale of the map (1:25000), we can calculate the map distance between town A and town B as follows:

Convert the real-world distance (2km) to a map distance using the scale: 2km x (1:25000) = 2km / 25000 = 0.00008 units on the map

Rounding the Map Distance

Since the map distance is a very small value (0.00008 units), we can round it to a more manageable value. Let's round it to 0.08 units.

Conclusion

In conclusion, the distance between town A and town B on the map with a scale of 1:25000 is approximately 0.08 units.

Understanding the Relationship Between Towns A and C

Now that we have determined the distance between town A and town B on the map, let's take a look at the relationship between town A and town C. Town C is 5km east of town A, which means that it is located at a 90-degree angle to town A.

Calculating the Map Distance Between Town A and Town C

Using the same scale (1:25000), we can calculate the map distance between town A and town C as follows:

Convert the real-world distance (5km) to a map distance using the scale: 5km x (1:25000) = 5km / 25000 = 0.0002 units on the map

Rounding the Map Distance

Since the map distance is a very small value (0.0002 units), we can round it to a more manageable value. Let's round it to 0.2 units.

Conclusion

In conclusion, the distance between town A and town C on the map with a scale of 1:25000 is approximately 0.2 units.

Understanding the Relationship Between Towns B and C

Now that we have determined the distance between town A and town C on the map, let's take a look at the relationship between town B and town C. Since town A is 2km due north of town B, and town C is 5km east of town A, we can use the Pythagorean theorem to calculate the distance between town B and town C.

Calculating the Map Distance Between Town B and Town C

Using the Pythagorean theorem, we can calculate the map distance between town B and town C as follows:

Calculate the difference in x-coordinates between town B and town C: 5km (east) - 0km (west) = 5km
Calculate the difference in y-coordinates between town B and town C: 2km (north) - 0km (south) = 2km
Use the Pythagorean theorem to calculate the map distance between town B and town C: √(5km^2 + 2km^2) = √(25km^2 + 4km^2) = √29km^2 = 5.385km
Convert the real-world distance (5.385km) to a map distance using the scale: 5.385km x (1:25000) = 5.385km / 25000 = 0.000215 units on the map

Rounding the Map Distance

Since the map distance is a very small value (0.000215 units), we can round it to a more manageable value. Let's round it to 0.22 units.

Conclusion

In conclusion, the distance between town B and town C on the map with a scale of 1:25000 is approximately 0.22 units.
