Usain Bolt ran the 2012 Olympic 100m race and 9.63 seconds if he runs at this rate on a road with a speed limit of 25 miles per hour how will his speed compared to the speed limit justify your answer 25 meter equals 40234 m a h r

Respuesta :

Let's calculate his velocity:

v = d/t

v = 100m/9.63s = 10.38m/s

The speed limit of the road is 25mi/h

Let's make a conversion:

[tex]\frac{25mi}{h}\times\frac{1609.34m}{1mi}\times\frac{1h}{3600s}=\text{ 11.18m/s}[/tex]

Therefore, we can conclude, that the speed limit is greater than the velocity of Usain Bolt, since:

11.18m/s > 10.38m/s
