Question

If 9 students sharpen 18 pencils in 2 minutes, how many students will it take to sharpen 18 pencils in 1 minute?

A. 2
B. 9
C. 18
D. 36
I have done the math and gotten the answer 18, but the question seemed way too easy to answer. Now I feel like it was a trick question. Did I get the right answer?

Answer 1

Yeah the answer is 18 because you would need double the people for half the time.

Answer 2

It has to be 18 because that's the only answer that seems right.
I hope I helped at all.
