A hawk soars at an altitude of 1,800ft. If the hawk descends to the ground in 45 min, what is the vertical speed?
Speed is measured by dividing distance by time. Miles per hour is a measure of speed. In this case, our distance unit is feet, and our time unit is minutes. To find the speed, we need to find distance/time, or ft/min.
1800ft/45min
40 ft/min
