Patchy and Remi are at the two ends of a hallway 100 meters apart, each running at a steady rate of 5 meters per second toward each other. At the same time, Flan is flying at 10 meters per second away from them in a futile attempt to escape. Flan starts where Remi is and flies until she reaches Patchy, at which point she turns around back toward Remi. In this way, Flan continues back and forth between her two captors. What is the total distance that Flan flies before getting caught?

This means that the when Patchy and Flan first meet, Flan will have traveled twice as far. This is equal to her flying 2/3 the length of the hallway.Subsequently, Flan will travel 2/3 the distance remaining between Patchy and Remi, which is now 1/3 the length of the hallway. The next distance will be 1/3 of that, and so on, each time with Flan traveling 2/3 of that distance.The sequence of lengths is then: 100×(2/3) m + 100×(1/3)×(2/3) m + 100×(1/3)x(1/3)×(2/3) m + ⋯This is a geometric series with rate 1/3 and initial term 100×(2/3), from which we can find the sum as:∑ₓ 100×(2/3)×(1/3)ˣ= 100×(2/3)×[1/(1 - (1/3))]= 100×(2/3)×(3/2)= 100 meters

 >> Mon May 13 10:32:04 2013 No.10880832 it would probably work quite well if the group translated X pages each, then dumped them into a collection. then everyone in the group would read the whole thing and suggest revisions until they're happy with it (some of them might understand certain phrases on someone else's page).
