I'm impressed that the student thought it through, but people are giving the grader too much of a hard time. If the question was instead, "If a machine can produce 2 cars in 10 minutes, how long does it take to produce 3 cars?" the teacher would be correct. If you've ever taken a standardized math test, it's easy to assume that the question is just a variation of that classic question. If I were a third-grader, I would have probably answered "???". So kudos to this kid.
- sosborn 13y agoYes, if it was a different question then the teacher might have been right. Kidding aside, this is probably a good demonstration of how shoe stringing our education budgets might not be the best idea.
- king_jester 13y ago> "If a machine can produce 2 cars in 10 minutes, how long does it take to produce 3 cars?" This question is also ambiguous, because there is no info about how long the operation takes, e.g. the machine may be parallelized and produce a 3rd car in 10 minutes along with the 2 others or that the machine may obey a non-linear increase in production time per unit.
