The jet is traveling at a speed of 285 miles per hour. In nine hours it would have traveled a distance of 2565 miles.
Step-by-step explanation:
To get the miles per hour, take the 570 miles and divide it by the two hours. that gets you 285 miles in one hour. that is your miles per hour. then you want the distance traveled in 9 hours. take the 285 miles per hours and multiply it my 9. That then leaves you with 2565 miles in nine hours.
