It takes (58)/(your speed in knots) hours.
It would take(486.627)/(boat's average speed in knots) hours
That's going to have a definite connection with the speed at which you travel. Here are a few examples: Speed = 1 knot. Time for 58 nm = 58hours Speed = 5 knots. Time = 11hours 36minutes Speed = 10 knots. Time = 5hours 48minutes Speed = 100 knots. Time = 34minutes 48seconds
It would take approximately 3 hours and 10 minutes to sail 19 miles at a speed of 6 knots. This calculation is based on the formula Time = Distance / Speed.
15 knots = 17.25 mph speed = distance / time, so time = distance / speed = 200 / 17.5 = 11.43 hours (approx).
That depends how fast it sails. If it sails with a speed of 25 knots -which I doubt-, it will take one hour. A more typical speed for that kind of vessel would be 8 knots, and then the trip would take a little over three hours.
Just like any other unit of distance, it all depends on your speed. For example . . . -- If your speed is one knot, then it takes 1 hour. -- If your speed is 60 knots, then it takes one minute. -- If your speed is 3,600 knots, then it takes one second.
* Use the formula: distance = speed x time. In this case, if you divide the distance by the speed, you get time.* "Knots" means "nautical miles per hour".
5 knots is 5.8 mph. Time = Distance / Speed Time = 20 miles / 5.8 miles per hour = 3.45 hours
