Calculating the Distance Repaired by Each Brigade

To calculate the distance repaired by each brigade per day, we can use the information provided in the question and the given data from the search results.

Let's start by defining the variables: - Let's assume the first brigade repairs x km of track per day. - The second brigade, working 2 hours less than the first, repairs (x - 2) km of track per day.

Given that both brigades together repair 4.5 km of track per day, we can set up the following equation: x + (x - 2) = 4.5

Solving for x: 2x - 2 = 4.5 2x = 6.5 x = 3.25

So, the first brigade repairs 3.25 km of track per day, and the second brigade repairs (3.25 - 2) = 1.25 km of track per day.

Answer:

- The first brigade repairs 3.25 km of track per day. - The second brigade repairs 1.25 km of track per day.
