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

the displacement will be 0and distance would be 280/80=3.5
400x3.5=1400m
400x3.5=1400m
how is the displacement zero?
hey
u said that at the end of 4min 40 secs he would have completed 3.5 rounds
so displacement is diameter
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
