🔍 Key Concepts

• Still-water speed vs. speed made good over the ground • Average current = Difference between actual progress and engine (ordered) speed • Using river mile marks (AHP – Above Head of Passes) to find distance run over the ground

💭 Think About

• From Baton Rouge to St. Catherine Bar Lt., what total distance in river miles have you actually traveled over the ground? • Given your ordered speed is 8.0 mph, how far should you have gone in the actual elapsed time if there were no current? • Once you have both distances (no‑current distance and actual over‑ground distance), how do you turn that difference into an average current over the whole run?

✅ Before You Answer

• Be sure you are using total distance from Baton Rouge to mile 348.6 AHP, not just a single reach. • Use elapsed time from departure at Baton Rouge to 0715; do not plug in any other time interval. • Compute speed made good over the ground (SMG) first, then compare SMG with 8.0 mph to get the average current.
