There are 60 seconds in a minute and 60 minutes in an hour; 60 * 60 = 3,600 seconds in an hour. 3,600 / 45 seconds = 80. And to cross-check: 80 mph * 5,280 feet in a mile = 422,400 feet per hour / 60 = 7,040 feet per minute / 60 = 117 1/3 feet per second * 45 seconds = 5,280 feet in 45 seconds.
Speed in miles per hour (mph) If something is traveling at 1 mph it moves 1 mile every hour. It is a slow walking pace. One hour walking at 1 mph moves you 1 mile. Miles per hour is often used for car speeds. Example: Highway speed is around 60 mph. One minute at 60 mph will move you 1 mile.
