At 0645, on the 17th of April, you pass Hole in the Wall Lt. (mile 373.4 AHP). What has been your average speed since departing the Exxon Refinery?
• Average speed formula: Speed = Distance / Time • Relationship between statute miles, time in hours, and mph (miles per hour) • Interpreting river mileages like "mile 373.4 AHP" as a distance reference point
• How long (in hours and decimal hours) has it been from your departure at the Exxon Refinery to 0645 on 17 April? • What total distance (in statute miles) have you traveled between the Exxon Refinery and Hole in the Wall Light (mile 373.4 AHP)? • Once you compute Distance / Time, which answer choice is closest to your calculated average speed?
• Be sure your time is converted fully into hours (minutes turned into a decimal of an hour) before dividing. • Confirm you are using statute miles, not nautical miles, since the answers are in mph. • Double‑check the starting and ending river miles so you’re using the correct distance between Exxon Refinery and mile 373.4 AHP.
