Answer:
The distance between two cities is 70 km.
Step-by-step explanation:
Given that,
The distance between two cities on a map is 3.5 centimeters.
It is also mentioned that the map uses a scale  in which 1 centimeter represents 20 kilometers.
We need to find the actual distance  between these two cities in kilometers.
1 cm = 20 km
3.5 cm = (3.5 Ă— 20) km
= 70 km
Hence, the distance between two cities is 70 km.
