while the displacement of sam is 0
because he ended where he started
as it is length than
50 = 2R
because pool would be as
long as its diameter
so R = 25m
which means circumference of pool is
2πR
2(3.141)(25)
157.05 metres
and for 3 complete laps
it becomes
3(157.05)
471.15 metres
now rounding it off to whole no.
we get 471 metres
