What we are asked to find out is speed per hour. To find speed, divide distance by time. Distance is 3000 ft and time is 1 3/4 hr. To make calculations easier, let us convert time into minutes. 1 hour is 60 minutes and 3/4 hour is 45 minutes. So total minutes is 105. Now let us divide 3000 by 105. We get 28.57 ft per minute. Now multiply this number by 60 to convert speed per minute into speed per hour. 28.57 * 60 = 1714 ft in 1 hour.
