Knots meters & time calculations

I know that this is clear as glass to u guys, but it is mud to me.
We are dealing in meters, kilometers & knots here & I can't get them sorted.

I did a trial run with a boat & wrote down the figures. using the online calculator it comes out correctly.

I did 1500 meters in 3:11 & the boat indicated 15kts

using my calculator I did: Speed X Time, 15kts X 3.183 = 47.74 what the heck is this number??? I went 1.5 km. or 1500 meters.

Distance divided by speed = time 1.5 divided by 15kts = .10 ??

Distance divided by time = speed 1.5 divided by 3.183 = .47

I have no idea what i'm doing here...maybe you really can't teach an old dog new tricks.. these meters kilometers & knots have me stopped.

I know that the minutes have to be converted to a decimal by dividing minutes by 60. Is it the same way for the seconds?
