The 1992 world speed record for a bicycle (human-powered vehicle) was set by Chris Huber. His time through the measured $200 \mathrm{~m}$ stretch was a sizzling $6.509 \mathrm{~s},$ at which he commented, "Cogito ergo zoom!" (I think, therefore 1 go fast!). In 2001 , Sam Whittingham beat Huber's record by $19.0 \mathrm{~km} / \mathrm{h}$. What was Whittingham's time through the $200 \mathrm{~m}$ ?

Key Concepts

Uniform Motion Kinematics

Uniform motion kinematics deals with motion at a constant speed, where the basic relation is distance = speed × time. This principle allows one to compute any of the three quantities when the other two are known, such as finding the speed given a distance and the time taken, and vice versa.

Unit Conversion

Unit conversion involves translating measurements from one unit system to another, which is vital in problems involving mixed units. For instance, converting speeds between kilometers per hour and meters per second (using the conversion factor 1 km/h ? 0.27778 m/s) ensures that all quantities are in compatible units for accurate calculations.

Rate-Time-Distance Relationship

The rate-time-distance relationship is the foundational concept in kinematics where the time to cover a given distance is computed by dividing the distance by the speed. This relationship is essential for analyzing situations where an increase or change in speed affects the time required to travel a fixed distance.
