Optional –Teacher measures out 300 feet along road and puts a cone at the start and finish a short distance from the roads edge. –From a hidden distance, students use a stopwatch to time the speed of cars from the start cone to the finish cone. –Speed = Distance (300 ft) divided by time (ft/s.) –Multiply by.681 (ft/sec to mph conversion) = mph –Over 30 mph is speeding in the village. –Create list of all the speeds and then average. –Does the village have a speeding problem?
