Journey time refers to the total duration it takes to travel from one location to another. This time can vary based on factors such as distance, mode of transportation, and traffic conditions. For example, a journey by car may take longer during peak hours compared to traveling by train, which often has a fixed schedule. Calculating journey time is essential for planning trips, whether for commuting to work or going on vacation. Tools like GPS and mapping apps can provide real-time estimates, helping travelers make informed decisions about their routes and departure times.
