Calculate the time it takes to travel a certain distance in nautical miles based on a speed in metres per second.

Formula

time = distance ÷ speed

Conversions

one nautical mile (nmi) = 1.852 kilometres (km)
one nautical mile (nmi) = 1.15077944802354 miles (mi)
one nautical mile (nmi) = 1852 metres (m)
one metre per second (m/s) = 3.28083989501312 feet per second (ft/s)
one metre per second (m/s) = 1.94384449244061 knots International (kn)
one hour (hr) = 60 minutes (min)
one hour (hr) =  3600 seconds (sec)

Example Calculation

How long will it take to travel 677.54 nautical miles at a speed of 12 metres per second?

First convert the nautical miles to metres;

677.54 *  1852 =  1254804.08

677.54  nautical miles equal 1254804.08 metres

Divide the distance of  1254804.08 metres by the speed of 12 metres per second to get the time in seconds;

1254804.08 ÷ 12 = 104567.01

It will take 104567.01 seconds to travel the 677.54 nautical miles at a speed of 12 metres per second.

Convert the 104567.01 seconds to hours by dividing by 3600 ( there are 3600 seconds in one hour);

104567.01 ÷ 3600 = 29.0464

It will take 29.0464 hours to travel the 677.54 nautical miles at a speed of 12 metres per second.
