Janiya is taking a road trip. The distance she plans to travel can be written as 3 * 10 ^ 2 kilometers, 3 * 10 ^ 5 meters, 3 * 10 ^ 7 centimeters, or 3 * 10 ^ 8 millimeters. Which distance uses the most appropriate units? (1 point)

Question

3 * 10 ^ 7 centimeters

3 * 10 ^ 3 millimeters

3 * 10 ^ 5 meters

3 * 10 ^ 2 kilometers

Answer 1

To determine which distance uses the most appropriate units for a road trip, we need to convert each of these measurements to a common unit and evaluate which is most practical for road travel:

1. 3 * 10^2 kilometers = 300 kilometers
2. 3 * 10^5 meters = 300,000 meters = 300 kilometers
3. 3 * 10^7 centimeters = 30,000,000 centimeters = 300 kilometers
4. 3 * 10^8 millimeters = 300,000,000 millimeters = 300 kilometers

While all of these distances are equivalent in terms of length (300 kilometers), kilometers is typically the most suitable unit for measuring distances in road travel.

Therefore, the most appropriate unit for Janiya's road trip is:

3 * 10^2 kilometers.
