Explanation:
- To find the speed in km/h, start by converting the distance and time into suitable units.
- The person crosses 1800 meters in 6 minutes.
- Convert 1800 meters to kilometers: \[1800 \, \text{m} = 1.8 \, \text{km}\].
- Convert 6 minutes to hours: \[6 \, \text{min} = \frac{6}{60} \, \text{h} = 0.1 \, \text{h}\].
- Speed in km/h is calculated using the formula: \[\text{Speed} = \frac{\text{Distance}}{\text{Time}} = \frac{1.8 \, \text{km}}{0.1 \, \text{h}} = 18 \, \text{km/h}\].
- Option 3: 18 km/h is the correct answer.
