Final answer:
The distance between the baseball stadium and the airport is 1.6×106 centimeters, which is best expressed in kilometers, as kilometers are used for measuring longer distances.
Step-by-step explanation:
The distance between the baseball stadium and the airport is 1.6×106 centimeters. To determine the most appropriate unit of measurement for this distance, we should consider the context and the size of the distance. Since kilometers are typically used to measure long distances, like a track or the distance around a block, and the given distance is quite considerable, the appropriate unit in this example would indeed be kilometers.
Converting centimeters to kilometers, we can use the conversion rate where 1 kilometer is equal to 100,000 centimeters. Therefore, we divide 1.6×106 centimeters by 100,000 to get the distance in kilometers:
1.6×106 cm ÷ 100,000 = 16 km.
Thus, for long distances such as the one between a stadium and an airport, kilometers are the most suitable unit of measurement.
