No the boat was sailing at an average speed
The average speed is(4 x the number of nautical miles the boat traveled in that time) knots.
depends on the size. a trailer boat=30mph a ski boat=60mph
a sail boat can go twice the speed of the wind in optimal conditions. speedboat 30-40
The average speed of boat in kilometers is per hour is 20 km /hr.

5 Knots/hr
The answer depends on the average speed of the boat and how long you can maintain that speed without stopping for refuelling, rest and so on.
2.16 m/s Just Average V-iniatial (0) and V final (4.32) so 4.32+0/2
It would take(486.627)/(boat's average speed in knots) hours
