Question

Two lines, a solid line and a dashed line, are drawn on a coordinate plane. The x-axis ranges from 0 to 6 in 1-unit increments, and the y-axis ranges from 0 to 10 in 1-unit increments.
The graph represents the precipitation over the last 5 hours in tenths of an inch. The x-axis represents time in hours, and the y-axis represents precipitation in tenths of an inch. It rained for the first 2 hours at a rate of 2 tenths of an inch per hour. It then transitioned to snow and snowed at a rate of 3 tenths of an inch per hour for the next 3 hours. How many tenths of an inch did it snow in total?

Answer 1

To calculate the total amount of snow, we first need to understand how long it snowed and at what rate.

1. **Time of snowfall**: It snowed for the last 3 hours (from hour 2 to hour 5).
2. **Rate of snowfall**: The rate of snowfall is 3 tenths of an inch per hour.

Now we can calculate the total snowfall:

\[
\text{Total snowfall} = \text{Rate of snowfall} \times \text{Time of snowfall}
\]
\[
\text{Total snowfall} = 3 \text{ tenths of an inch per hour} \times 3 \text{ hours}
\]
\[
\text{Total snowfall} = 9 \text{ tenths of an inch}
\]

The total amount of snow is **9 tenths of an inch**. Therefore, the correct response is:

**9 tenths of an inch**.
