Please can someone help me solve today's puzzle...my head is throbbiing!!!
A ship is battling against a strong tide to safety. It uses eight gallons of fuel every hour and sails at 16mph in still conditions. The ship is 84 miles from land and the floe
w against it is 7mph. It has 75 gallons of fuel left. How much fule will remain when itv reaches land?
So... Ok... throw out the stuff we don't need... this ship is making 9mph and will take 9.3 (9 hours and 18 minutes) to complete. At 8 gallons per hour it will use 74.66 gallons, and will have roughly have .4 (4/10ths) of a gallon left...
