Need help with a Physics problem.

<p>Ok so the problem is calculating the distance if the average speed is 110km/h and the change in time is 2 seconds.
So i know you convert the seconds to hours
110 km/h=d/(2/3600)
then multiply the time and you get
d=.0611111
But i was wondering can someone explain to me how i would solve if i converted the hours to seconds instead and convert it back to hours. Just wanted to know how because when i tried i kept getting the wrong answer.</p>
