Question 275909: If it takes 3 students, 3 minutes, to solve 3 problems..... then how long will it take 1 student to solve 2 problems? Answer by josmiceli(19441) (Show Source):
You can put this solution on YOUR website! If it takes 3 students 3 min to solve 3 problems,
Then, it takes 1 student 3 times as long to do the same job
so far:
It takes 1 student 9 min to solve 3 problems
Therefore it takes 1 student 3 min to solve 1 problem
Therefore it takes 1 student 6 min to solve 2 problems
