1 knot = 1 nautical mile per hour
time = distance ÷ speed
= 140 nautical miles ÷ 20 nautical miles per hour
= 7 hours.

The speed of water flow is the current. The speed of vessels traveling over water may be measured in 'knots" (meaning nautical miles per hour).
141 nautical miles
Knots are used to measure speed (for boats, aeroplanes, wind or water/current.) One knot is one sea mile per hour. It is equal to 1.1508 statute miles (1.852 km) per hour or 1.687 ft (0.5144 m) per second. 400 miles per hour = 347.584 knots
5,143 nautical miles
A nautical unit of measure equal to one tenth of a nautical mile is known as a cable or nautical cable. In nautical terms, a cable is approximately 608 feet or 185.2 meters long. It is commonly used for measuring distances at sea, especially when referring to the depth of water.
The distance from Holland, Michigan, to Chicago, Illinois, is approximately 80 nautical miles. This measurement can vary slightly depending on the specific route taken over water. Nautical miles are often used in maritime contexts to account for the curvature of the Earth.
Knots is for water and Miles per hour is for land
Wind speed is often measured in knots because this unit is based on nautical miles, which are more relevant for maritime and aviation navigation. Knots provide a standardized measure that aligns with the distances traveled over water, making it easier for sailors and pilots to calculate their speed and distance. Additionally, using knots helps maintain consistency in international contexts, as it is widely recognized in meteorology and maritime operations.
Sustained winds of 12 to 19 knots are considered moderate winds, typically associated with a gentle breeze to a moderate breeze on the Beaufort scale. This wind speed can cause small waves on water surfaces and may influence outdoor activities like sailing or flying kites. In nautical terms, 12 knots is approximately 14 miles per hour, while 19 knots is about 22 miles per hour. Such winds can also have an impact on weather conditions, potentially leading to partly cloudy skies and scattered cloud formations.
A water-going vessel, such as a boat or ship.
The distance between the above places is approximately equal to 170 nautical miles. To convert miles to nautical miles, multiply the miles by 0.86. This is point to point straight distance. The actual distance will change according to the route.
