Answer 2

Task Analysis

The task involves determining whether two groups of engineers can prepare a rocket for launch within a specified time frame. The first group takes 3 hours to prepare the rocket, while the second group takes 4 hours. The question is whether the two groups combined can prepare the rocket for launch within 2 hours.

Solution

To solve this problem, we can calculate the combined rate at which the two groups work and then determine if they can complete the task within 2 hours.

Let's denote: - R1 as the rate of work for the first group (in rockets per hour) - R2 as the rate of work for the second group (in rockets per hour)

The combined rate of work for both groups is given by: R1 + R2

Calculation

Given: - First group's time to prepare the rocket (T1) = 3 hours - Second group's time to prepare the rocket (T2) = 4 hours - Total time available (T) = 2 hours

We can calculate the rates of work for each group as follows: - R1 = 1 rocket / 3 hours - R2 = 1 rocket / 4 hours

The combined rate of work for both groups is: R1 + R2 = 1/3 + 1/4

Conclusion

By calculating the combined rate of work, we can determine whether the two groups can prepare the rocket for launch within 2 hours.
