There are to many variables that go into that question . Boat weight , motor size , prop pitch and diameter , form of the boats hull ( flat or a v hull ).
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!
row boat, paddle boat, motor boat, sail boat, cargo boat, speed boat, and fishing boat
a geared motor has gears to to give different power and speeds as in a car a gearless motor is a direct drive that uses the speed of the engine only for power and speed when driven, such as in 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.
If it doesn't speed up, then you can't say that is becomes accelerated. Accelerated means that the speed changes.If the motor is pushing all the time, and the boat maintains its speed, then that means that there is a force of equal magnitude pulling backwards. This would be the friction with the boat, against the water.
