Question

What is the rate and unit rate of 90 inches of snow over 9 days?

Answer 1

To find the rate of snow accumulation, you simply divide the total amount of snow by the total number of days.

**Total snow:** 90 inches
**Total days:** 9 days

**Rate:**
\[ \text{Rate} = \frac{\text{Total snow}}{\text{Total days}} = \frac{90 \text{ inches}}{9 \text{ days}} = 10 \text{ inches/day} \]

So the rate of snow is 10 inches per day.

The **unit rate**, which is the same in this case because we are already simplifying to a per-day basis, remains:

**Unit Rate:** 10 inches per day.
