7.5 centimeters on the map represents an actual distance of 25 kilometers given that a scale on a map shows that 3 centimeters represents 10 kilometers. This can be obtained by using the formula of scale.
<h3>What number of centimeters on the map represents an actual distance of 25 kilometers?</h3>
The scale of a map is the ratio of distance on the map to the ratio on the ground. Ratio scale is very accurate.
Scale = Distance on the map/Distance on the ground
Here in the question it is given that,
- A scale on a map shows that 3 centimeters represents 10 kilometers
- A certain number of centimeters on the map represents an actual distance of 25 kilometers
We have to find the number of centimeters on the map that represents an actual distance of 25 kilometers.
Let the required number of centimeters be x.
By using the formula of scale we can write that,
⇒ Scale = Distance on the map/Distance on the ground
Scale = 3 cm/10 km = x cm/25 km
x = 3×25/10 cm
⇒ x = 7.5 cm
Hence 7.5 centimeters on the map represents an actual distance of 25 kilometers given that a scale on a map shows that 3 centimeters represents 10 kilometers.
