Question

the distance between two cities on a map is 3.5 centimeters. The map uses a scale in which 1 centimeter reprecents 20 kilometers. what is the actual distance between these two cities in kilometers?

Answer 1

70 kilometers

Explanation:

Set up a proportion where x is the actual distance

`(1)/(20)` =
`(3.5)/(x)`

Cross multiply:

x = (20)(3.5)

x = 70

So, the actual distance is 70 km
