It depends if you get too tired, what kind of boat you are rowing in, and all that complicated information.
At 20 mph how long would it take to drive one mile?
How long will it take to get to Amsterdam from new york on a boat
One mile at 60mph would take just one minute.
If you are going "one mile per hour", it takes exactly one hour to go a mile.
one month
if you walk 4 miles an hour how long would it take you to walk a mile
It will take 45 seconds.
That depends on how fast you go.
It depends on how how fast the wind is
It would depend on how fast you were travelling. For a set speed, one mile on the moon would take the same time as one mile on Earth.
A mile by boat is the same length as a mile by car, foot or airplane: 5,280 feet. If you're asking how long it takes to go a mile by boat, that depends on the speed it is going. Whoops - I think I misinterpreted your question, so I'm amending my answer. A mile by boat is stil 5,280 feet, but there's something else called a "nautical mile" which is used mostly by sea and air navigators who can't measure long distances just by laying a ruler against a map, because any flat map trying to portray the spherical earth distorts distances. A nautical mile is equal to one minute of arc of longitude at the equator (or one minute of arc of a meridian, one of the imaginary circules around the earth the goes through the North and South Poles). This is about 6,076 feet.
One and one half months.
