Jon's MENSA Question of the Day--posted by JRJ on 7/10/2006
The young fellow was extremely eager to join his girlfriend for dinner. It was a 24-mile run upstream to visit her. His boat's speed would be 14 miles per hour but the current is running 4 miles an hour against him. He just filled his tank and he knows he has 20 gallons, but he uses up 6 gallons per hour. Will he make it or will he run out of gas?
