Since I've had to convert several numbers to metric now to make sense of them, I though I'd put the conversions here for anyone else that's in the same boat:

183.9 MPH = 296.0 KPH (record speed, average over 1 mile)

100 MPH = 160 KPH (approximate speed at which tow rope detached and she began accelerating under her own power)

128 ft = 39 m (linear distance travelled per crank revolution)
