A toy car travels on a circular track at a constant speed of 0.50 m s⁻¹. It passes a point on the track at time t = 0 and takes a time of 40 s to travel once around the track. The magnitude of the average velocity of the car between t = 0 and t = 20 s is v₂₀. The magnitude of the average velocity of the car between t = 0 and t = 40 s is v₄₀. What are v₂₀ and v₄₀?

1. Av₂₀ = 0.32, v₄₀ = 0
2. Bv₂₀ = 0.32, v₄₀ = 0.32
3. Cv₂₀ = 0.50, v₄₀ = 0
4. Dv₂₀ = 0.50, v₄₀ = 0.50
