Problem Analysis

We are given that one team can pave 1200 meters of road in 7 days, while another team can pave the same distance in 14 days. We need to determine how long it will take for both teams to pave the road together.

Solution

To solve this problem, we can calculate the rate at which each team paves the road and then combine their rates to find the total time required.

Let's start by calculating the rate at which each team paves the road. We can use the formula:

Rate = Distance / Time

For the first team, the rate is 1200 meters / 7 days = 171.43 meters per day.

For the second team, the rate is 1200 meters / 14 days = 85.71 meters per day.

Now, let's combine the rates of both teams to find the total rate when they work together. We can simply add their rates:

Total rate = Rate of Team 1 + Rate of Team 2

Total rate = 171.43 meters per day + 85.71 meters per day = 257.14 meters per day.

Finally, we can use the combined rate to calculate the time required to pave the road. We can use the formula:

Time = Distance / Rate

Substituting the values, we get:

Time = 1200 meters / 257.14 meters per day ≈ 4.67 days.

Therefore, it will take approximately 4.67 days for both teams to pave the road together.

Answer

Working together, the two teams will be able to pave the road in approximately 4.67 days.
