Asked by Lisa
Two cars are driving toward each other on a straight and level road in Alaska. The BMW is traveling at 115 km/h north and the VW is traveling at 54.0 km/h south, both velocities measured relative to the road. At a certain instant, the distance between the cars is 11.6 km. Approximately how long will it take from that instant for the two cars to meet?

Relative velocity is
115+54 = 169 km/h.
t=s/V(rel) =11.6/169=0.068 h=4.12 min
115+54 = 169 km/h.
t=s/V(rel) =11.6/169=0.068 h=4.12 min
