3) How many yards are in 20
feet? Give the answer as a
mixed number.

The cities are actually  190 km apart.

Step-by-step explanation:

Consider the provided information.

It is given that a map scale is 1 cm : 50 km.

We need to find the distance between the two cities if they are 3.8 cm apart.

To find the actual distance between the two cities using the map, multiply each side of the relationship by  3.8

3.8 × 1 cm  : 3.8 × 50 km

3.8 cm : 190 km

The cities are actually  190 km apart.
