Find the distance between Riverside and Milton if they are 12 cm apart on a map with a scale of 4 cm : 21 km.

Answer 1

To find the actual distance between Riverside and Milton, we need to convert the map distance to the actual distance using the scale.

Given that the scale is 4 cm : 21 km, we can set up the following proportion:

4 cm / 21 km = 12 cm / x km

Cross-multiplying:

4 cm * x km = 21 km * 12 cm

Simplifying:

4x = 252

Dividing both sides by 4:

x = 63

Therefore, the actual distance between Riverside and Milton is 63 km.
