## How do you calculate speed and distance from sailing?

**Answers**

- You are trying to find your speed so use the formula for speed: S = D/T. The distance to be covered is 10 miles and the time it will take is 2 hours. …
- You are trying to find distance, so use the formula: D = S x T. The speed is 6 knots and the time is 3 hours. …
- You are trying to find time here: T = D/S.

Calculate elapsed time of voyage: (Distance traveled is divided by the speed to find time in hours.) (**Divide the hours by 24 to find the number of days**.)

## How long does it take to sail 13 miles?

13 nautical miles / 5 knots = 2.6 hours = **2h 36m**.

## How do you calculate sea distance?

The fixed relationship between distance, speed and time helps sailors calculate the distance the vessel is expected to travel in a given time. The formula being used by sailors is **60 x D = S x T** which is expressed as 60D = ST.

**Distance equals speed multiplied by time**. If two variables are known the third can be found. and can be remembered by the address: 60 “D” Street. Time is entered in minutes, speed in knots and distance in nautical miles (the same formula will work for statute miles and kilometres).

To find the Distance use the formula of **D=ST/60**. You would multiply the Speed of 14 by the Time of 40 and divide by 60, giving you a distance of 9.33 nautical miles.

## How far can you sail in a day?

How many nautical miles can you sail in a day? On average, sailboats can sail **up to 100 NM (115 miles or 185 km)** in one day when they run downwind. If the engine is used at all, this distance can increase to 130 NM on longer passages. With shorter passages, 60 NM is more typical.
