That depends on the speed at which one is traveling.
Depends on speed of boat.
It depends on the speed of the boat
That depends on your speed.
That depends on your speed.
If the miles are nautical ones, then it takes (3)/(the boat's speed in knots) hours. If the miles are statute ones, then it takes (2.6053)/(the boat's speed in knots) hours.
It depends on the speed of the boat you know miles per hour
That depends on the speed at which one is traveling.
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.
That depends on the speed at which one is traveling.
That depends on the speed at which one is traveling.
The rate of crossing depends on the speed the boat is traveling, not on the distance it has to travel. 25 miles could probably be crossed in approximately forty-five minutes or less.
That cannot be calculated without knowing the average speed over that distance.
