A traffic patrol officer uses a UAV with a camera to measure the transit time of vehicles between two-mile markers to measure the speed of vehicles on a major highway. A certain vehicle passes through the two-mile markers with an average speed of 77 miles per hour, and the distance between the markers is 5280 ft ± (50 ft). If the officer uses a stopwatch to measure the transit time, and his reaction time uncertainty to any single event is 0.05 sec, what is the uncertainty in the aircraft-based speed measurement?
