Problem Analysis

To solve this problem, we need to find out how many meters of road still need to be repaired. We are given the total length of the road, the length of the repaired section, and we need to calculate the remaining length of the road that needs to be repaired.

Solution

To find the remaining length of the road that needs to be repaired, we can subtract the length of the repaired section from the total length of the road.

Let's calculate it step by step:

1. Total length of the road: 1,200 meters. 2. Length of the repaired section: 300 meters.

To find the remaining length of the road that needs to be repaired, we subtract the length of the repaired section from the total length of the road:

Remaining length of the road that needs to be repaired = Total length of the road - Length of the repaired section

Remaining length of the road that needs to be repaired = 1,200 meters - 300 meters

Remaining length of the road that needs to be repaired = 900 meters

Therefore, there are 900 meters of road that still need to be repaired.

Conclusion

The remaining length of the road that needs to be repaired is 900 meters.
