SUMMARY
The discussion focuses on calculating the total distance and displacement of a car traveling in one dimension. The car moves north at 30 m/s for 30 minutes and then south at 40 m/s for 15 minutes. The correct approach involves converting the speeds to consistent units, calculating the distance for each segment using the formula d = speed x time, and then determining displacement by considering the direction of travel. The key takeaway is that distance is the total path traveled, while displacement is the net change in position.
PREREQUISITES
