To estimate the vehicle's speed just before it hit a road median, a traffic engineer measured the length of skid marks made by the vehicle's brakes. The length of skid marks for multiple trials: 495 ft, 513 ft, 504 ft, and 531 ft. assume a level road with default reaction time and friction.( speed in mph, one decimal answer)
