Uncle Anaconda
Uncle Anaconda saddled up his mare, Maggie in preparation for a month long hunting trip up at Python Peak, and planned to stay at the old lodge which is 117 miles away. They started out early Sunday morning and arrived at the lodge eight days later on Monday evening. Uncle Anaconda calculated that on each day of the trip, he and Maggie travelled one mile less than they had the day before. How many miles did Uncle Anaconda and Maggie travel on the last Monday of the trip?
Answer
9 miles.The equation is as follows, with x being the last days travel.
x + (x + 1) + (x + 2) + (x + 3) + (x + 4) + (x + 5) + (x + 6) + (x + 7) + (x + 8 ) = 117
9x + 36 = 117
9x = 81
x = 9

Wouldnt this be more of a logic or math problem?
That's what I thought too
same here
In the first place, it is certainly a Math teaser and in the second place the answer is that not enough information is given to solve it. The solution is satisfied as long as the distance travelled on the first and last days totals 26 miles. So 9 and 17 or 10 and 16 or whatever! Assuming they travelled at least 1 mile each day there are 25 different answers in whole miles, and if they can travel a fraction of a mile on any day (why not) then there are an infinite number of answers).
It's definitely math.
x + (x + 1) + (x + 2) + (x + 3) + (x + 4) + (x + 5) + (x + 6) + (x + 7) + (x + = 117
9x + 36 = 117
9x = 81
x = 9
x + (x + 1) + (x + 2) + (x + 3) + (x + 4) + (x + 5) + (x + 6) + (x + 7) + (x + = 117
9x + 36 = 117
9x = 81
x = 9
Good One!

if he travels 117 miles in 8 days that averages 14.625 miles a day as a starting point, now you can identify that even 1000th of a mile is still an increase. So this answer is wrong. Plus in their equation they use 9 factors of X
