28. Swimming one lap in a pool is
defined as going across a pool and
back again. If a swimmer swims 3
laps in 9minutes, how can his average
velocity be zero? *
His average velocity is zero because
his total distance is zero.
His average velocity is zero because
his total displacement is zero.
His average velocity is zero because
the number of laps completed is an
odd number.
His average velocity is zero because
O the velocity of each successive lap
is equal and opposite.
