A math has a scale of 3 cm: 18 km. If Riverside and Smithville are 54 km apart then they are how far apart on the map?
Cross multiply and solve for x.
3/18 = x/54
18x54
To find out how far apart Riverside and Smithville are on the map, we can use the scale provided in the question: 3 cm represents 18 km.
First, let's find the ratio of cm to km: 3 cm represents 18 km.
Dividing both sides of the ratio by 3, we get: 1 cm represents 6 km.
Now, we can use this ratio to calculate the distance on the map for the actual distance between Riverside and Smithville:
Since Riverside and Smithville are 54 km apart, we divide 54 km by 6 km/cm to find how many centimeters on the map each kilometer represents:
54 km ÷ 6 km/cm = 9 cm
Therefore, on the map, Riverside and Smithville are 9 cm apart.
