Speed distance time calculations
Hey guys
Im pretty cool with doing the speed distance time stuff.... however, i get stuck when some crazy division is needed.....
E.G - At 9 mph, how long does it take to travel 6 miles?
Now, I know that the answer is 40MPH ( I used a calculator.. ) however, how on earth do you find the mile per minute in your head, as this requires you to do 9/60 (0.15)..... If anyone has a really simple way of doing this, please share. I have stage one on the 5/11/10!!!! thanks
