Calculate the time it takes to travel a certain distance in nautical miles based on a speed in feet per second.
time = distance ÷ speed
one nautical mile (nmi) = 1.852 kilometres (km) one nautical mile (nmi) = 1.15077944802354 miles (mi) one nautical mile (nmi) = 6076.11548556429 feet (ft) one foot per second (ft/sec) = 0.3048 metres per second (m/sec) one foot per second (ft/s) = 0.592483801295897 knots International (kn) one hour (hr) = 60 minutes (min) one hour (hr) = 3600 seconds (sec)
How long will it take to travel 1200 nautical miles at a speed of 44 feet per second?
First convert the nautical miles to feet;
1200 * 6076.11548556429 = 7291338.58
1200 nautical miles equal 7291338.58 feet
Divide the distance of 7291338.58 feet by the speed of 44 feet per second to get the time in seconds;
7291338.58 ÷ 44 = 165712.24
It will take 165712.24 seconds to travel the 1200 nautical miles at a speed of 44 feet per second.
Convert the 165712.24 seconds to hours by dividing by 3600 ( there are 3600 seconds in one hour);
165712.24 ÷ 3600 = 46.031
It will take 46.031 hours to travel the 1200 nautical miles at a speed of 44 feet per second. 46 hr - 1 min - 52 sec
