You cannot convert hours into miles because you have no idea how fast they were driving. There could be a huge difference between someone who drives really slow over 200 engine hours and someone who drives really fast over the same 200 hours. It does not take into account the distance traveled, only the hours the engine has been run.
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 distance between the above places is approximately equal to 1247 nautical miles. To convert miles to nautical miles, multiply the miles by 0.86. This is point to point straight distance. The actual distance will change according to the route.
distance = rate * time 190 miles = rate * 10 hrs r=190 miles/10 hrs = 19 mph 28.5 miles = 19 mph * t t=28.5miles/19 mph=1.5 hours
195 miles
The speed of the boat is 26.67 miles per hour. This is calculated by dividing the distance traveled (20 miles) by the time taken (45 minutes converted to hours, which is 0.75 hours).
The distance between the above places is approximately equal to 276 nautical miles. To convert miles to nautical miles, multiply the miles by 0.86. This is point to point straight distance. The actual distance will change according to the route.
That depends on the boat, and on the engine. If it's an outboard engine, it takes about 2 minutes. If it's built in, then it could take hours, or perhaps days. Or longer, if the bolts have gotten rusty.
Time = Distance/Speed = 10 miles/20 miles per hour = 0.5 hours or 30 minutes.
The answer varies significantly based on the condition of the boat, engine hours (and rebuilds), and location. For a boat in very good condition (kept indoors) with an engine rebuilt or replaced in the last 500 hours, I would suggest around $4k.
Boats speed = 24 miles per hour.Current speed = 4 miles per hour.
if a boat cruises at 10 mph in still water, it can go 30 miles in 3 hours. if it takes the boat 7 hours to go that same 30 miles, it's speed must be 4.28 mph (30 mi / 7 hrs) which would make the current 5.71 mph
It would take(486.627)/(boat's average speed in knots) hours
