20 knots = 23 MPH. 5 knots = 23/4 MPH. Time required = 230 M/(23/4) = 40 Hrs.So the time required is 40 hrs
42 knots = 48.333 mph
2 MPH = 1.73795248 Knots (Roughly)
20 knots is about 23.02 miles per hour (knots x 1.150779448 = mph).
120 Knots is 138.12 miles per hour.
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.
The knot is a unit of speed equal to one nautical mile per hour. Therefore moving at 3 knots it would take 350/3 = 116.6666666666667 hours to go 350 nautical miles.
It takes a bit over 3 hours to sail 19 miles at 6 knots
90.37352913333875 hours or 90 hours 22 minutes 24.7 seconds at a consistan 6 knots
One knot is equal to 1 nautical mile per hour. So for 535 nautical miles at 6 knots, 535 nautical miles/6 knots=535 nautical miles/6 nautical miles per hour=535/6 hours which is about 89.2 hours (89 hours and 10 minutes).
34 miles
(1,832)/(average ground speed in knots) hours.
3 hours 33 minutes.
