The world distance record for riding a standard bicycle in 1 h is 49.70 km, set in 2005 in Russia (Figure P8.23). A fixed-gear bike was used, which means that the bike effectively had only one gear. Assuming that the rider pedaled at a constant speed, how fast did the rider pedal the front gear/sprocket in rpm to achieve this record?
