~~~~~~~~~~~~~~~~~~~~~~



        Calculations in the post by @mananth are incorrect/inaccurate.

        I came to bring a correct accurate solution.



2 minutes and 30 seconds = 2 and 1/2 minutes = 5/2 minutes = (5/2 )/60 = 5/120 of an hour.


speed = d/t = 42 / (5/120) = 1008 kilometers per hour. &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<U>ANSWER</U>


Solved correctly.
