28. Swimming one lap in a pool isdefined as going across a pool andback again. If a swimmer swims 3laps in 9minutes, how can his averagevelocity be zero? *His average velocity is zero becausehis total distance is zero.His average velocity is zero becausehis total displacement is zero.His average velocity is zero becausethe number of laps completed is anodd number.His average velocity is zero becauseO the velocity of each successive lapis equal and opposite.
