Answer 3

Calculating Construction Time for the Second House

To calculate the number of days it took to build the second house, we can use the information provided.

Let's denote: - \( x \) as the number of days it took to build the first house. - \( x + 4 \) as the number of days it took to build the second house.

Given that the workers built the first house in 9 days, we can set up the equation: \[ x = 9 \]

According to the given information, the second house took 4 days longer to build than the first house. Therefore, the number of days it took to build the second house can be expressed as: \[ x + 4 \]

Substituting the value of \( x \) from the first equation, we get: \[ 9 + 4 = 13 \]

Therefore, the workers took 13 days to build the second house.
