🔍 Key Concepts

• Understanding how to convert distance run and speed made good into an estimated time of arrival (ETA) • Using the 24-hour clock and correct date change when a trip crosses midnight • Carefully tracking start time, elapsed time, and arrival time on river mile problems (AHP – Above Head of Passes)

💭 Think About

• From your last known time and position on the river, how many miles do you still have to go to reach mile 782.2 AHP? • At the speed given in the problem, how long (in hours and minutes) will it take to cover that remaining distance? Show that calculation. • When you add that elapsed time to your starting clock time, do you stay on the same day, or do you cross over to the next calendar day?

✅ Before You Answer

• Be sure you are using AHP miles correctly (are you going upriver or downriver, and are you subtracting/adding miles in the right direction?). • Double-check your time addition: convert fractions of an hour to minutes and correctly handle any carry over if minutes exceed 60. • Confirm that your final time format matches a 4-digit 24-hour time plus the correct calendar date (12 Sept).
