Travel time refers to the duration it takes to move from one location to another. This time can vary based on factors such as distance, mode of transportation, and traffic conditions. For example, traveling by car may take longer during rush hour compared to traveling on a train or a plane. Calculating travel time is essential for planning trips, whether for leisure or work. It helps individuals estimate when they will arrive at their destination, allowing for better scheduling. Tools like GPS and mapping apps can provide real-time updates on travel time, considering current road conditions and potential delays.
