Okay, I've heard it too. Forever. 10 pounds, times 20 miles, equals 200 pounds.
Hmmm...
What about metric!?
10 lbs x 20 mph = 200 lbs
4.5 kg x 32 km/h = 144 kg = 317 lbs
Okay, I know the 'formula' doesn't match up exactly with mph and pounds... that would be *too* perfect. And I know it's a decent rule of thumb just to give people an idea... but really, IS there a true formula (boy, for a teacher I sure don't know my stuff, do I?) that equates this? And what IS the formula? Or is it really weight in pounds times speed in miles?
