A car travels north at 30.0 m/s for 10.0 min. It then travels south at 40.0 m/s for 20.0
min. What are the total distance the car travels and its displacement?
distance north = 30 m/s * 10 min * 60 s/min = 18000 meters north
south = 40 *20 * 60 = 48000 meters south
distance = 18 kilometers + 48 km = 66 km = 66,000 meters
displacement = 48 - 18 = 30 Km = 30,000 meters SOUTH
