Respuesta :

The formula should be (2πr)/T. r=radius T=time. if time is in seconds the formula would look like this
[tex] \frac{2\pi \times 105}{60 \times 2} [/tex]

Speed = (distance covered) / (time to cover the distance)

Distance covered = (π · diameter) = 210π meters

Time to cover the distance = 2 minutes or 120 seconds

Speed = (210π meters) / (120 seconds)

Speed = 5.5 meters/sec
