You, on the other hand, have 17:45 to travel 100.7 km (54.4 nm) to meet the convoy. Then,
S = D/T = 54.4 nm / 17:45 = 3 knots. <---Your speed.
You said the time was 19:52...plus the 17:45 = 13:37 the next day.
If you travelled at 5 kn. you'd get there a little earlier ... to set up your ambush, or, stay off enough to shadow them 'til dark, then move in to attack.

Thank you. I don't wanna seen stupid, but how do I calculate nm from km? Reason being, I would like to design a spreadsheet to do the calculations for me. Did you use .54 to get nm?
