Answer 2

Problem Analysis

We are given that there is a highway leading to a spaceport, and we need to repair 1,200 meters of the road. It is mentioned that 3/4 of the section has already been repaired. We need to determine how many meters of the road are left to be repaired.

Solution

To find the number of meters left to be repaired, we need to subtract the length of the already repaired section from the total length of the road.

Let's calculate the length of the already repaired section: - The total length of the road is 1,200 meters. - 3/4 of the road has already been repaired.

To find the length of the already repaired section, we can multiply the total length of the road by 3/4: 1,200 meters * 3/4 = 900 meters.

Now, we can find the number of meters left to be repaired by subtracting the length of the already repaired section from the total length of the road: 1,200 meters - 900 meters = 300 meters.

Therefore, there are 300 meters left to be repaired.

Answer

There are 300 meters left to be repaired.
