What is the distance in NM covered by the vessel during the acceleration from 3 knots to 13 knots

To find the distance covered by the vessel during the acceleration, we need to calculate the average speed and multiply it by the time taken.

Average speed = (Initial speed + Final speed) / 2

= (3 knots + 13 knots) / 2

= 8 knots

Let's assume the time taken for acceleration is 1 hour.

Distance covered during acceleration = Average speed * Time taken

= 8 knots * 1 hour

= 8 nautical miles

Therefore, the vessel covers a distance of 8 nautical miles during the acceleration from 3 knots to 13 knots.
