🔍 Key Concepts

• Speed = Distance ÷ Time relationship (use statute miles and hours here) • How to calculate elapsed time between two calendar dates and times (from 1710 on the 27th to 1200 on the 29th) • Using river mile marks (AHP) to find the remaining distance to destination

💭 Think About

• First, work out exactly how many hours you have between your current time and 1200 on the 29th—write it out step by step over the two days. • Next, determine the distance remaining from Kings Point Lt. (mile 439.8 AHP) to Redneb Services Dock using the mile marks on the river chart or table. • Finally, plug your total distance and total available time into the Speed = Distance ÷ Time formula, and compare your result to the answer choices.

✅ Before You Answer

• Be sure your total time is in hours (convert days and minutes properly). • Confirm your distance is in statute miles using the mile marks AHP (do not mix with nautical miles or km). • After calculating speed, check that your result is reasonable (slowing down from normal river speeds) and matches one of the choices without heavy rounding.
