Whittingham's time through the 200 m was 5.55 seconds.

Step-by-step explanation:

Huber's peed = 200m / 6.509s = 30.72m/s

1 meter per second = 3.6 km per hour

30.72 m/s = $30.72\times36.=110.6$ km/hr

Sam's speed is 110.6 + 19 = 129.6 km/hr

1 km per hour = 0.2778 meter per second.

So, 129.6 km/hr = $129.6\times0.2778$ = 36m/s

So, Sam Whittingham's time through the 200 m was =

$\frac{200}{36}= 5.55$ seconds.
