The problem in the image is asking for the number of street lamps along a 45-meter road, with the distance between two consecutive lamps being 4 meters.

### Problem Breakdown:
- **Distance between each lamp**: 4 meters.
- **Total length of the road**: 45 meters.

To calculate the number of lamps, follow this logic:
- There will be one lamp at the start of the road.
- For every additional 4 meters, another lamp will be placed.

### Solution:
If the total length of the road is 45 meters, and the distance between consecutive lamps is 4 meters, we need to calculate how many gaps (or spaces) of 4 meters fit into 45 meters and then account for the first lamp at the start.

\[
\text{Number of gaps} = \frac{45}{4} = 11.25
\]

Since you can't have a fraction of a gap, round this down to 11. This means there are 11 gaps, which means 12 lamps (one at the start, and one after each gap).

So, the correct answer is **12 lamps**.
