How do you find the distance between two points?

Take the square root of D2 to find D, the actual distance between the two points. For example, if D2 = 41, then D = 6.403, and so the distance between (-3, 7) and (1, 2) is 6.403.

How do you convert km to CM on a map?

To work out the distance on the map, we need to divide this length by 50000. 4.5 km = 4500 m = 450000 cm. Dividing 450000 cm by 50000 gives a distance on the map of 9 cm. Alternatively, we could have just remembered that each 0.5 km in real life is 1 cm on the map.

What distance does 1 cm represent in KM?

100,000 cm
There are 100,000 cm in 1 km so we can think of this as 1 cm representing 0.5 km or as 2 cm representing 1 km.

How do you find the distance between two points on a map?

Go to maps.google.com.

1. Right-click the starting point and select “Measure distance.”
2. Click the end point (or second point) to create a direct line from the original point and get the distance between the two.
3. If you want to measure the distance between multiple points, simply click the next point on the map.

How to calculate the scale and distance of a map?

Map Scale and Distance Calculator. Calculate scale, distance on the map or real distance on Earth. Please enter two values, the third will be calculated. An example: on a map with the scale 1:20000, 3 centimeters accord to 0.6 kilometers in reality. 1 cm ⇒ 20000 cm. 3 cm ⇒ 20000 * 3 cm = 60000 cm = 600 m = 0.6 km.

How do you find the distance between two towns with 15 cm?

If 1cm = 3km, then 1*15cm = 3*15km. 15 centimetres on the map is 45 kilometres on the ground, so the ground distance between the two towns is 45km. As the distance between the two points on the map is 15 cm you just multiply 3 km by 15 → 45 kilometers

What is the scale of 1 cm on a map?

A map has a scale of 1 cm : 20 km. Two cities are 2.5 cm apart on the map. To the nearest tenth of a kilometer, what is the actual distance corresponding to the map distance? | Socratic

What is the distance between 20000 cm and 600 m?

3 cm ⇒ 20000 * 3 cm = 60000 cm = 600 m = 0.6 km. The scale is rounded to integers, the distance of the map to 0.1, the real distance to 0.001.
