Ships used chip logs before modern mechanics and that is where the term “knots” comes from. For ships and airplanes or airships travel in knots not miles per hour. So I guess we have several first questions What is the difference between a knot and a mile? How are they measured precisely? What does a chip log look like? If they didn’t have speedometers did they have clocks? If no clocks what did they use to measure time at sea?
This is a great way to really get going with time and distance.
