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
A knot is a nautical mile per hour. So this would be 1.48 hours.
400/10 = 40 hours.
15 nautical miles is equal to 17.262 statute miles.
About 2 hours 16 minutes at 65 mph
about 4 hours is you don't dog it.
918 miles is 1,477.4 kilometers.
80 Roman miles is 73.56 statute miles.
3 hours
About 10.41 days at 6 knots.
Knots (not Knots per hour) are nautical miles per hour. So the answer is 902 divided by 7 which is 128.86 hours
11½ days
2½ days
14 days and 14 hours.
14 hours 44 minutes.
1375 divided by 22 = hours
One hour.
1500/11 hours
36/14 hours
No way to tell. Knots is a measurement of speed, nautical miles is distance. 16 knots is 16 nautical miles/hour, so it'd depend on how long the craft would keep going.
