During a race, a runner travels four times around a circular track and finishes back at the starting line. If the track is 400 meters long, what is the runner's DISTANCE?

• 0 meters

• 400 meter

• 800 meters

• 1600 meters

During a race, a runner travels four times around a circular track and finishes back at the starting line. If the track is 400 meters long, what is the runner's DISPLACEMENT?

• 0 meters

• 400 meters South

• 800 meters Northwest

• 1600 meters East

What is the speed formula?

• speed = displacement/distance

• speed = distance/time

• speed = time/distance

• speed = distance/displacement
