You pass Hole in Wall Light at 1200, 24 May. What is your ETA off the Mhoon Landing Gauge if you average 6.5 mph?
• Distance off the river chart between Hole in Wall Light and Mhoon Landing Gauge • Speed-time-distance relation: Time = Distance ÷ Speed (using statute miles and mph) • Converting travel time in hours and tenths into hours and minutes, then adding to the departure time and calendar date
• First, determine how many statute miles you must travel between Hole in Wall Light and Mhoon Landing Gauge from the inland river chart or table. How will that distance relate to your average speed of 6.5 mph? • Once you compute the travel time in hours, how do you convert the decimal part of an hour into minutes correctly (for example, 0.5 hr, 0.7 hr, etc.)? • After you get the total elapsed time, how do you carry hours forward across midnight and possibly into multiple days from 24 May to find the correct date and time on 26 May?
• Be sure you are using statute miles (sm), not nautical miles, since the speed is given in mph on the river. • Double‑check your time conversion from decimal hours to hours and minutes; a small mistake here will shift the ETA significantly. • Confirm your date change: start at 1200, 24 May, then add the full travel time step by step (first to midnight, then whole days, then remaining hours) before matching to the closest choice.
