Asked by AXEL

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.)

Her speed is 4.4 m/s, and her velocity is 0 m/s.
Her speed is 1.1 m/s, and her velocity is 0 m/s.
Her speed is 0 m/s, and her velocity is 2400 m/s.
Her speed is 4.4 m/s, and her velocity is 4.4 m/s.

Distance = 4 laps × 400 m = 1600 m. Time = 6 min = 360 s.
Speed = distance/time = 1600/360 ≈ 4.44 m/s ≈ 4.4 m/s.
Displacement = 0 (she ends where she started), so average velocity = 0 m/s.

Answer: Her speed is 4.4 m/s, and her velocity is 0 m/s.
