A typical speedboat can go pretty fast, with top speeds around 40 knots (46 mph). Only the really expensive boats can go faster, as they are essentially modified racing boats that can reach 80 knots or better.
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.
30km/hr
Information about the speed of the car provides no information whatsoever about the speed of a boat!
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
because the name speed boat means its a fast boat why else would it be called a speed boat
