Two cars are driving toward each other on a straight, flat Kansas road. The Jeep Wrangler is traveling at 84 km/h north and the Ford Taurus is traveling at 43 km/h south, both measured relative to the road. What is the velocity of the Jeep relative to an observer in the Ford?

Vjf= 84+43 km/hr South. Think on that.
what does Vjf stand for?
84-43km/h= 41km/h because north is in quadrant one which means it is positive however west is in quadrant four which means it is negative.
