On a map, 1cm represents 4.5km. What is the actual distance between two towns which are 4cm apart on the map?
4cm x 4.5 km = 18 km
To find the actual distance between the two towns, we need to convert the distance on the map to the actual distance using the given scale.
Given: 1cm on the map represents 4.5km in real life.
If 1cm represents 4.5km, then 4cm represents 4 * 4.5km = 18km.
Therefore, the actual distance between the two towns is 18km.
To find the actual distance between two towns on the map, you need to convert the map scale into real-world measurements. In this case, the scale states that 1cm on the map represents 4.5km in real life.
First, determine how many kilometers are represented by 1cm on the map. Since 1cm represents 4.5km, you divide the distance on the map (4cm) by the scale factor (1cm = 4.5km).
4cm / 1cm = 4
So, according to the map scale, the distance of 4cm on the map represents 4 times the scale factor in real life.
Next, multiply the distance on the map (4cm) by the scale factor (4.5km).
4cm * 4.5km = 18km
Therefore, the actual distance between the two towns is 18 kilometers.
