Distances refer to the measurement of space between two points. This can be expressed in various units, such as meters, kilometers, miles, or feet. Distances can be measured in straight lines, known as "as-the-crow-flies," or along a path, which may be longer due to curves or obstacles. In everyday life, understanding distances is important for navigation, travel, and planning. For example, when driving from City A to City B, knowing the distance helps estimate travel time. Distances also play a crucial role in fields like geography, engineering, and sports, where precise measurements are essential.
