the scale on a map is 1 cm: 7 km. if two cities are 15 cm apart on a map, what is the actual distance in the cities?
15 cm * (7 km / 1 cm) = 105 km
To find the actual distance between the cities given the scale on the map, you can use the scale ratio.
The scale indicates that 1 cm on the map represents 7 km in reality.
So, if two cities are 15 cm apart on the map, we need to find the equivalent distance in kilometers.
To do this, we can set up a proportion:
1 cm (on map) = 7 km (actual distance)
15 cm (on map) = x km (actual distance)
We can solve this proportion by using cross-multiplication:
1 * x = 15 * 7
x = 105 km
Therefore, the actual distance between the cities is 105 km.
To find the actual distance between the two cities, you can use the scale provided on the map.
Given that the scale on the map is 1 cm:7 km, it means that 1 centimeter on the map represents 7 kilometers in actual distance.
If the two cities are 15 cm apart on the map, we can set up a proportion to find the actual distance between the cities:
1 cm on the map represents 7 km in actual distance
15 cm on the map represents x km in actual distance
Setting up the proportion:
1 cm / 7 km = 15 cm / x km
Cross multiplying, we get:
1 * x = 7 * 15
x = (7 * 15) / 1
x = 105 km
Therefore, the actual distance between the two cities is 105 kilometers.
