In 17.2 seconds, a shopping cart is pushed 15.6 meters towards the right. What is the velocity of the cart?

Answer 1

Your question isn't specific enough. If the cart is moving at a constant velocity, the answer would be 15.6/17.2 = 0.907m/s However, you don't state it is a constant velocity.

You could also say that its average velocity is 0.907m/s for that period of time.

But since the wording is not specific enough, the cart could be accelerating or decelerating, or it could even have stopped right at the 15.6m mark. Essentially any speed (short of the speed of light) is possible.
