  • Circumference of a circle = 2π x Radius

Distance around the track = 2π x 12 meters = 24π meters

If the track is a circle, tangential velocity = its speed.

  • Speed = (distance covered) / (time to cover it)

Speed = (24π meters) / (1.2 minutes)

Speed = 20π meters/minute   (about 1.05 meter/second)
