Lila is a track and field athlete. She must complete four laps around a circular track. The track itself is a 400 meter track and it took her 6 minutes total to complete.Which best describes her speed and velocity? (There are 60 seconds in 1 minute.)

Four laps cover 4 × 400 = 1,600 meters, and 6 minutes is 360 seconds. Her average speed is 1,600 ÷ 360 ≈ 4.4 m/s. Because she finishes where she started after completing the laps, her displacement is zero, so her average velocity is 0 m/s. The correct choice is A: speed 4.4 m/s and velocity 0 m/s.
