Since we need to convert “miles per second” to “miles per hour,” we first need to find out how many seconds there are in a hour. We know that there are 60 seconds in a minute, and if we wanted to do an hour we would have to do 60 * 60 which is 3600 seconds, therefore, 1 mi/57.1 sec = (1 mi/ 57.1 sec)(3600 sec/1 hour)
