38kilometres

38 kilometres (38 km) is a unit of length in the metric system equal to 38,000 metres. It is approximately 23.62 miles. The kilometre is widely used to express distances between towns, along road networks, and for geographic or planning purposes.

In practical terms, 38 km is a moderate travel distance. At typical driving speeds around 60 km/h, a 38 km trip takes about 0.63 hours, or roughly 38 minutes. At 100 km/h, it takes about 0.38 hours, or around 23 minutes. Walking a distance of 38 km at a pace of about 5 km/h would take roughly 7.5 to 8 hours. These examples illustrate how 38 km functions as a convenient unit for estimating travel times and planning routes.

History and notation: The kilometre is a derived unit of the International System of Units (SI), formed from kilo- (1,000) and metre. The concept and its adoption varied by country as the metric system spread in the 19th and 20th centuries. The symbol is "km." Spelling variations exist: "kilometre" is common in British English, while "kilometer" is standard in American English.

Usage context: The kilometre remains the standard measure for longer land distances in most countries outside the United States. It is used in transportation planning, mapping, road signage, and geographic reporting. The term is often encountered in discussions of travel times, distances between cities, and regional planning.
