If snow falls at a rate of $1 \mathrm{~mm}$ every 6 minutes, then how many hours will it take for $1 \mathrm{~m}$ of snow to fall?
(A) 33
(B) 60
(C) 26
(D) 10
(E) 100
Since $1 \mathrm{~mm}$ of snow falls every 6 minutes, then $10 \mathrm{~mm}$ will fall every $6 \times 10=60$ minutes. Since $10 \mathrm{~mm}$ is $1 \mathrm{~cm}$ and 60 minutes is 1 hour, then $1 \mathrm{~cm}$ of snow will fall every 1 hour. Since $1 \mathrm{~cm}$ of snow falls every 1 hour, then $100 \mathrm{~cm}$ will fall every $1 \times 100=100$ hours.
