Question

The 1992 world speed record for a bicycle (human-powered vehicule) was set by Chris Huber. His time through the measured 200m stretch was a sizzling 6.509 s, at which he commented "Cognito ergo zoom". In 2001, Sam Whittingham's beat Hubert's record by 19.0km/h. What was Whittingham's time through the 200m? (hint: d=rt).

Expert Solution

Step 1

$Time taken by Chris Huber in 1992 to cover 200 m stretch = 6.509 seconds Using formula, Speed×time = distance S p e e d \times 6.509 = 200 = \frac{200}{6.509} = 30.7266 \frac{m}{s} Speed of Chris Huber = 30.7266 \frac{m}{s}$
