Question7 Some teachers are running for a charity fundraiser. A science teacher runs 9 laps in 18 minutes. A math teacher runs 12 laps in 36 minutes. Which statements are true? (A) The ratio of laps to minutes for the science teacher is $9: 18$. (B) The science teacher runs faster than the math teacher per lap. (C) The math teacher runs faster than the science teacher per lap. (D) The ratio for laps to minutes for the math teacher is $12: 36$. (E) Both teachers run at the same rate.

Studdy Solution
Determine if both teachers run at the same rate:
Since $\frac{1}{2} \neq \frac{1}{3}$, both teachers do not run at the same rate.
Based on the analysis, the true statements are: (A) The ratio of laps to minutes for the science teacher is $9: 18$. (B) The science teacher runs faster than the math teacher per lap. (D) The ratio for laps to minutes for the math teacher is $12: 36$.
The false statements are: (C) The math teacher runs faster than the science teacher per lap. (E) Both teachers run at the same rate.
