The basketball coach tells his team to run sprints back and forth across the court, which is 30 m long. they start at the left end of the court, run back and forth 6 times, then end back at the left end of the court where they began. what distance did they run? what is their displacement?

Distance is the total length of an object's path. Displacement is the overall change in position, ie. how far an object is from its initial position.

The court is 30 m long, so a path going back and forth once is 60 m long. Going along this path 6 times totals 360 m.

The end point is the same as the starting point, so the displacement is 0 m.

well clustered together.
