How long does it take to travel 35 nm at 30 knots?

Answer 1

1 knot is defined as a speed of 1 nm/h

So obviously it takes one hour to travel 30 nm ... which leaves another 5 nm to be covered.

One hour has 60 minutes, so in one minute, you are travelling 30 nm / 60 minutes , which equals 0.5 nm

With this knowledge, you can easily deduct that, to travel the remaining 5 nm, you'll need ten minutes.

If you sum it up, you get 1 hour = 60 minutes plus 10 minutes = 70 minutes.

That's how long it takes to travel 35 nm at 30 knots ....

If you like an easier answer, its 35/30*60.
