Let’s check out your problem:

An arctic cold front caused the temperature to drop a total of $20^{\circ} \mathrm{C}$. The temperature was dropping at a rate of $10^{\circ} \mathrm{C}$ per hour. The temperature dropped an equal amount each hour.$\newline$The following equation describes this situation.$\newline$$$-20 \div-10=2$$$\newline$What does $2$ tell us?$\newline$Choose $1$ answer:$\newline$(A) The temperature dropped $20^{\circ} \mathrm{C}$ in $2$ hours.$\newline$(B) The temperature dropped $10^{\circ} \mathrm{C}$ in $2$ hours.$\newline$(C) The temperature is dropping at a rate of $2^{\circ} \mathrm{C}$ per hour.
