Answer 2

The actual distance between the two cities is 28 kilometers

Explanation:

A map has a scale of 3.5 inches = 20 kilometers

Distance between two cities on the map = 4.9 inches

We can use the unitary method in this question to get the actual distance between two cities

∵ 3.5 inches on the map = 20 kilometers

∴ 1 inch distance on the map =
`(20)/(3.5)` kilometers

∴ 4.9 inches on the map =
`(20)/(3.5)* 4.9`

= 28 kilometers

Therefore, the actual distance between the two cities is 28 kilometers.
