Answer:
Explanation:
The circumference of a circle of radius r is given by
... C = 2πr
When r = 1 m, then
... C = 2π(1 m) = 2π m
The relation between time, distance, and speed is ...
... time = distance/speed
... time = (2π m)/(1 m/s) = 2π s

Comment on the scenario
We have a hard time imagining what sort of scenario this is modeling, as it appears the "boat" is rotating in such a way as to place the barnacle above and below the water level. This problem may be nonsensical, but at least it is workable. (Some aren't.)
