Travel distance refers to the total length of the path taken when moving from one location to another. It can be measured in various units, such as miles or kilometers, depending on the context. Travel distance is important for planning trips, estimating travel time, and determining fuel costs. In transportation, travel distance can vary based on the mode of travel, such as driving, walking, or cycling. Factors like road conditions, traffic, and routes can also affect the actual distance traveled. Tools like GPS and mapping applications help users calculate the most efficient travel distance for their journeys.
