A comet takes 4 hours to cruise 200,000 kilometers through the Solar System. Why can't we determine the velocity of the comet?

We can't figure out the comet's speed.


We don't know the comet's direction.


We don't know how the comet got there.


We don't know how far the comet traveled.

Respuesta :

We don't know the comet's direction.

please mark brainliest.

Answer:

The correct answer is option b: We don't know the comet's direction.

Explanation:

Hello!

Let's solve this!

To calculate the speed, we need to know the initial position and the final position.

We also need the initial time and the final time.

In this case we have the distance traveled, but not from where and where the comet came from.

After the analysis, the correct answer is option b: We don't know the comet's direction.
