When a cyclist pedals he turns a gear called a chainring The angular velocity of the chainring will determine the linear speed at which the chain travels The chain connects the chainring to a smaller gear called a sprocket which is attached to the rear wheel see figure below The angular velocity of the sprocket depends upon the linear speed of the chain The sprocket and rear wheel rotate at the same rate and the diameter of the rear wheel is 700 millimeters The speed at which the cyclist travels is determined by the angular velocity of his rear wheel Use this information to answer the following Rear wheel Sprocket diameter Chain Chainring diameter A pro cyclist is climbing Mount Ventoux equipped with a 150 millimeter diameter chainring and a 95 millimeter diameter sprocket If he was pedaling at a rate of 100 revolutions per minute find his speed in kilometers per hour 1 km 1 000 000 mm Round your answer to one decimal place km hr
