Understanding the Units of Measurement
To determine which of the given options is the largest, we need to convert them into the same unit. The options are given in different units: kilometers (km), meters (m), and centimeters (cm).
Unit Conversions
- 100 km
This is already in kilometers.
- 200 m
To convert meters to kilometers:
200 m = 200 / 1000 = 0.2 km
- 100 m
Similarly, convert 100 meters to kilometers:
100 m = 100 / 1000 = 0.1 km
- 200 km
This is also already in kilometers.
Comparison of Values
Now, let's summarize the values converted to kilometers:
- 100 km = 100 km
- 200 m = 0.2 km
- 100 m = 0.1 km
- 200 km = 200 km
Identifying the Largest Value
Comparing these values:
- 100 km
- 0.2 km
- 0.1 km
- 200 km
Clearly, 200 km is the largest value among all the options.
Conclusion
Thus, the correct answer is option 'D', which is 200 km. Understanding unit conversions is crucial in comparing different measurements effectively.
