Question

If a car was cruising down the highway at 80 km/hr, how fast would the people inside the car be traveling?

Answer 1

Because the people in the car are attached to the vehicle, the people inside the vehicle are going the same speed as the vehicle.

Hope this helps! :)

Answer 2

The people inside the car are at rest (speed = zero) relative to the car, moving 80 km/hr relative to the pavement, and slightly slightly less relative to a worm slithering on the road in the same direction as the car.
