The distance will be 2π×(400÷2)m & the displacement is 400m

mythri43: no thats okay

mythri43: diameter and displacement

lisha4597: Do u have notice the time....

lisha4597: In that time the athlete will be in the other end of the starting position

mythri43: yeah

mythri43: thats what i am also telling

lisha4597: I know

the displacement will be 0and distance would be 280/80=3.5
400x3.5=1400m

mythri43: how is the displacement zero?

mythri43: hey

mythri43: u said that at the end of 4min 40 secs he would have completed 3.5 rounds

mythri43: so displacement is diameter

mythri43: because after 3 full rounds he will be at starting point and the other half round he will be at the exact opposite of circular track so it is diameter
