The scale on a map is 1 cm = 30 km. The map distance between two towns is 3.5 cm.
What is the actual distance between the two towns?

The actual distance between the two towns is 105 km

Step-by-step explanation:

Lets use a proportion for this scenario

1/30 = 3.5/?

We see that the numerator is multiplied by 3.5, from 1 to 3.5

So we do the same to the denominator

30 x 3.5 is 105 km

So your answer is 105 km
