Calculating the Number of Poles on the Road

To calculate the total number of poles installed on the 1000-meter stretch of road, we can use the given information that poles are installed at the edges of the stretch and at intervals of 50 meters.

Number of poles at the edges: - There will be 2 poles at the edges of the 1000-meter stretch.

Number of poles at 50-meter intervals: - The 1000-meter stretch will have 20 intervals of 50 meters each.

Total Number of Poles

- Total number of poles = Number of poles at the edges + Number of poles at 50-meter intervals - Total number of poles = 2 + 20 - Total number of poles = 22

Therefore, there are 22 poles installed in total on the 1000-meter stretch of road.
