A test of a driver’s perception/reaction time is being conducted on a special testing track with wet pavement and a driving speed of 80 km/h. When the driver is sober, a stop can be made just in time to avoid hitting an object that is first visible 120 m ahead. After a few drinks under exactly the same conditions, the driver fails to stop in time and strikes the object at a speed of 40 km/h. Determine the driver’s perception/reaction time before and after drinking
