Jacob strode up 24 steps in 12 seconds to reach his apartment on the second
floor. How many steps did he climb in 9 seconds?

I think the answer is 3

Step-by-step explanation:

I know the 24 can go into 12 twice, and I know 3 can go into 9 three times. Don't know if this is the real way to solve it, but I do think this answer is correct. If not I am truly sorry. Let me know either way. :) Thanks!
