what grade is this because apparently i like to know what grade it is before i solve it
If we use mile or something else it will be hard to measure in sky .
Because the mile or meters too short for the space,
Galaxy and stars are too long far away from us if we use mile or meter,
It till be take like miliion year to measure.
It would probably stop moving. Earth has motion and we do do. without the world moving, there would be No wind at all.
