In an experiment, a shearwater (a seabird) was taken from its nest, flown 5150 km away, and released. The bird found its way back to its nest 13.5 days after release. If we place the origin at the nest and extend the +x–axis to the release point, what was the bird's average velocity in m/s (a) for the return flight

If you are driving 85 km/h along a straight road and you look to the side for 2.0 s, how far do you travel during this inattentive period?

A particle at t₁ = ― 2.0 s is at 𝓍₁ = 5.2 cm and at t₂ = 3.4 s is at 𝓍₂ = 8.5 cm. What is its average velocity over this time interval? Can you calculate its average speed from these data? Why or why not?
