Explanations:Map scale is a fundamental concept in cartography and geography. It is used to represent real-world distances on a smaller scale on a map. The scale can be expressed in various ways, such as a ratio, a verbal scale, or a graphical scale. In this question, we are given the real-world distance and the distance on the map, and we need to calculate the scale.
The formula for calculating the scale is:
Scale = Real Distance / Map Distance
In this case, the real distance is 1500 km, and the distance on the map is 15 cm. To find the scale, we divide the real distance by the map distance:
Scale = 1500 km / 15 cm
Performing the division:
Scale = 100 km/cm
This means that 1 cm on the map represents 100 km in the real world. Therefore, the correct answer is 100 km.
It is important to note that the units must be consistent when performing the calculation. In this case, we are using kilometers for the real distance and centimeters for the map distance. The resulting scale is in kilometers per centimeter, which is a common way to express map scales.
Understanding map scales is crucial for interpreting maps accurately. It allows us to measure distances on the map and convert them to real-world distances. This skill is particularly important in fields such as geography, cartography, and navigation.
