Guessing your current speed (Hire Boat)

Here's a simple grid for converting distance and time to speed (start in left column, work along until you get the right time, and then look up).

 

I decided against calculating to the nearest second, given what it is for (use on tidal waters, to give you a clue when you should expect to arrive at the next marker). It shows nautical miles and knots, but works fine for miles and mph of course.

I withdraw my outrageous assertion your figures were wrong. Having looked again I can't imagine why I suggested this. They look fine to me now.

 

I think there must have been something wrong with the alcohol...

 

My apologies.

Don't worry about it, made me re-check & wonder if there was something blindingly obvious that I'd forgotten. No harm in that.

Cheers.
