Where Should You Go?

Math brain teasers require computations to solve.

 Puzzle ID: #37258 Fun: (2.72) Difficulty: (2.3) Category: Math Submitted By: MarcM1098

In your last adventure, you left a broken-down supply truck in the middle of a desert, near the equator. You and a Desert Patrol Vehicle (DPV) have been airlifted to the disabled truck so you can repair it and bring it back to camp.

Because of recent attacks, the whole area is under a communications blackout. You must return to camp before sunset so that they can visually identify you. If you return after sunset, they will shoot first and ask questions later.

The repairs take longer than expected, and you realise that driving the truck, you cannot make it to your base camp in time. You will have to return to camp in the DPV (which can travel faster) and leave the truck for another day.

Your camp is 500 miles to the south, but there are also two other camps in the area: one is 520 miles west, the other is 480 miles east.

Where should you go to reach a camp before sunset? The DPV can travel 80 mph, and you have plenty of fuel. It is now 12:50 PM and you know that at your base camp, the sun sets at 7:00 PM. One piece of trivia springs to mind: the circumference of earth is about 24900 miles at the equator.

 MarcM1098 Jul 07, 2007 This continues the story that began in the teaser "How Far Can You Go?". HarryPutter Jul 10, 2007 I never got it! mosca Jul 10, 2007 Good teaser! The math is well explained! meg19_83 Jul 19, 2007 too much info to take in took away from the idea mbunap Jul 20, 2007 Didn't need any math. Saw the sun setting later in the west immediately. Entertaining and fun. javaguru Jan 14, 2009 Yeah, it's too bad you needed to supply the "trivia". Very entertaining nonetheless. Bonus question: If he continues at a constant rate of speed, how far would he get by sunset? South is easy: 493 1/3 miles, but east and west are a bit trickier since you are either moving towards or away from the setting sun. I'll leave the answer for the reader to figure out.
