The distance between two cities on a map is 3.5 centimeters. The map uses a scale in which 1 centimeter represents 20 kilometers.

What is the actual distance between these two cities in kilometers?
A.55 km
B.60 km
C.65 km
D.70 km

To find the actual distance between the two cities, you can use the scale given on the map.

### Given:
- The distance on the map = 3.5 cm
- The scale is 1 cm = 20 km

### Steps:
1. Multiply the distance on the map by the scale:
   \[
   3.5 \, \text{cm} \times 20 \, \text{km/cm} = 70 \, \text{km}
   \]

The actual distance between the two cities is **70 kilometers**, so the correct answer is:

**D. 70 km**

2. How would the answer change if the map distance was 4.5 cm?
3. If the actual distance was 90 km, what would the map distance be?
4. How could you convert this answer into miles if 1 km = 0.621 miles?
5. How does changing the scale affect the map's level of detail?

**Tip:** Always double-check the scale before calculating map distances to avoid errors!
