18% of a kilometer can be calculated by multiplying 18% with the length of a kilometer.
[SOLUTION]
180 \text{ meters}
[STEP-BY-STEP]
1. Convert percentage to a decimal.
- 18% is the same as 0.18.
18\% = \frac{18}{100} = 0.18
2. A kilometer is 1,000 meters.
1 \text{ kilometer} = 1000 \text{ meters}
3. Calculate 18% of a kilometer in meters.
0.18 \times 1000 = 180
4. Therefore, 18% of a kilometer is:
180 \text{ meters}
