Real pirates? if real, they couldn't go really fast because they were only steered by sails and maybe paddles. if its modern boats, really fast due to advances in technologies with the addition of high powered engines.
10 knots=11.5 mph, but some ships might have exceeded at 12 knots=13.8 mph.
The time it takes to travel 4,000 miles by ship depends on the vessel's speed. For a cargo ship traveling at an average speed of 20 knots (about 23 mph), it would take approximately 8-9 days to cover that distance. However, if the ship is slower, such as a cruise ship at around 15 knots (about 17 mph), it could take around 10-12 days. Weather conditions and port stops could also affect the total travel time.
35.7 mph
A train is traveling at 60 mph. If the rate of speed increases 4 mph each hour, how long will it be before the ship is traveling at a rate of 80 mph?
Most travel about 15 miles per hour. However, in 24 hours a ship could travel 360 miles during that time. At 20 mph, it would travel 480 miles.
If you could maintain a steady 600 mph in a straight line, you could be on the moon in only 397 days.
Very likely. In extreme cases hail can be larger than grapefruit and fall at over 100 mph.
12,000 mph is very wrong the speed is a lot closer to 17,500 mph
length units could not be converted into speed units
Yes. Many dinosaurs could run.
Apollo 10 reached 24226 mph
Speed is no longer a design criteria for cruise ships.
