Two cars are driving toward each other on a straight road.The BMW is traveling at 100 km/h North and the VW is traveling at 42 km/h South. At a certain , the distance between the cars is 10 km.Approximately how long will it take from that instant for the two cars to meet? [ hint: consider a reference frame in which one of the cars is at rest].
