John was eager to join his girlfriend Mary for dinner. It was a 24 mile trip upstream to visit her. His boat’s speed is 14 mph in still water but the current is running 4 mph against him. He just filled his 20 gallon tank and he knows he uses 6 gallons per hour. Will he make it to Mary’s house or will he run out of gas?
For an extra challenge, but no prize: With the same conditions above, except the current is now with him, and without adding gas to his tank, how long will it take him to get home?
Please e-mail Lester Dickey with your answer and your name, phone number, and the organization for which you work. Or call Barbara Buck at 624-9501. The winner will be drawn from all the correct entries and will receive a FREE donated pizza, either from CJ’s Pizza or from the EDOC Cafeteria. All answers must be in no later than the 14th of the month.
Last issue's challenge brought 63 submissions, with 30 having correct answers. The winner, chosen by random drawing, is Richard Washburn of Maine Revenue Services.
The answers to last issue’s Challenge: My assumption was that "to make change" means to use coins in value less than a dollar, so the dollar, and higher denomination coin were not used. I could have stated this, but I wanted the "Challenge" to actually be a little challenging! Based on that assumption, the most money I can have in my hand is $1.19. This can be accomplished in three ways: 3Q, 4D, 4P (11 coins); 1H, 1Q, 4 D, 4 P (10 coins); and 1Q, 9D, 4P (14 coins). Each of these answers was accepted.
