Miles per hour (mph) is a unit of speed expressing the number of miles traveled in one hour. Determining this value involves dividing the distance covered, measured in miles, by the time taken to cover that distance, measured in hours. For instance, if a vehicle travels 120 miles in 2 hours, its speed is calculated as 120 miles / 2 hours = 60 mph.
Understanding speed calculation is crucial in various fields, including transportation, logistics, and sports. It allows for efficient planning of travel routes, estimation of arrival times, and analysis of performance. Historically, the need to quantify speed has been essential for navigation, trade, and the development of transportation technologies.
