The car moves along the road to the bridge at a speed u = 72 km / h. At the initial moment, the distance from the car to the beginning of the bridge is l = 200m. At what distance s from the middle of the bridge will the car be located after t = 1 minute, if the length of the bridge is L = 400 m

72 km / h = 72 * 1000/3600 = 20 m / s In a minute will travel 20 * 60 = 1200 m Initial distance to the middle of the bridge 200 + 400/2 = 400m S = 1200-400 = 800m
