        Calculations in the post by @mananth are incorrect, leading to wrong answer.

        I came to bring a correct solution.



Let the time taken to return be x hours (LA to Boston)
The time to go will be x+2/3 hours
600x = 525(x+2/3)
600x = 525x + 350
75x = 350
x = 350/75 = 4 2/3 hours


The distance will be &nbsp;&nbsp;4 2/3 * 600 = 2800 miles.   &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<U>ANSWER</U>
