 A map has a scale of 1 : 60 000. Find the actual distance for each scaled distance.
a 9 cm b 8 mm



Given the scale of 1 : 60,000, this means that 1 unit on the map represents 60,000 units in reality. To find the actual distance, you multiply the scaled distance by 60,000.

### a) 9 cm on the map
\[
\text{Actual distance} = 9 \, \text{cm} \times 60,000 = 540,000 \, \text{cm}
\]
Now, convert centimeters to kilometers (since 100,000 cm = 1 km):
\[
540,000 \, \text{cm} = \frac{540,000}{100,000} = 5.4 \, \text{km}
\]
So, the actual distance is **5.4 km**.

### b) 8 mm on the map
First, convert 8 mm to cm (since 1 cm = 10 mm):
\[
8 \, \text{mm} = 0.8 \, \text{cm}
\]
Now, calculate the actual distance:
\[
\text{Actual distance} = 0.8 \, \text{cm} \times 60,000 = 48,000 \, \text{cm}
\]
Convert centimeters to kilometers:
\[
48,000 \, \text{cm} = \frac{48,000}{100,000} = 0.48 \, \text{km}
\]
So, the actual distance is **0.48 km**.
