Sharpen your pencils on a cold night..

This just for info...

100 km/h is 62.137 MPH and 120 km/h is 74.564 MPH.

Next, I have no idea what this has to do with anything.

Next, why is it expressed in km/h?...I have no idea. Sent to me by a guy that challenged my math knowledge. Challenge, heck, I wouldn't have a clue but sounds like fun if you are into math and etc. Supposed to send answer later and that will probably make little or no sense either.

Is this some classic math problem there is no answer to? Just asking.
