The question asks to find the average speed of an object between 11:00 and 12:00 based on the graph provided.

To calculate the average speed, we use the formula:

\[
\text{Average Speed} = \frac{\text{Change in Distance}}{\text{Change in Time}}
\]

### Step 1: Identify the change in distance (Δd)
- At 11:00, the distance is approximately 30 km (based on the graph at the start of section **B**).
- At 12:00, the distance is approximately 50 km (based on the graph at the end of section **C**).

\[
\Delta d = 50 \, \text{km} - 30 \, \text{km} = 20 \, \text{km}
\]

### Step 2: Identify the change in time (Δt)
- The time interval is from 11:00 to 12:00, which is a 1-hour interval.

\[
\Delta t = 1 \, \text{hour}
\]

### Step 3: Calculate the average speed
\[
\text{Average Speed} = \frac{20 \, \text{km}}{1 \, \text{hour}} = 20 \, \text{km/h}
\]

However, the provided options do not include 20 km/h. Since this discrepancy exists, it is likely due to a misreading of the intervals or the choices not matching up exactly with the graphical readings.
