Answer 1

To determine which distance uses the most appropriate units for a road trip, we should consider the distance in kilometers, meters, centimeters, and millimeters.

1. 3 × 10² kilometers = 300 kilometers
2. 3 × 10⁵ meters = 300,000 meters
3. 3 × 10⁷ centimeters = 30,000,000 centimeters
4. 3 × 10⁸ millimeters = 300,000,000 millimeters

For a road trip, the most appropriate unit is typically kilometers, as it is a standard unit for measuring longer distances. So, between all the options, 3 × 10² kilometers (300 kilometers) is the most suitable for a road trip.

The best choice is: 3 × 10² kilometers.
