Answer 3

Solution:

To solve this problem, we can use the concept of work rate. The work rate is the amount of work done per unit of time. In this case, we'll calculate the work rate of each earthworker and use it to determine how much work they can complete in 5 hours.

Let's start by calculating the work rate of each earthworker.

The first earthworker's work rate is: 2 meters / 2 hours = 1 meter per hour

The second earthworker's work rate is: 2 meters / 2 hours = 1 meter per hour

Now, let's calculate the combined work rate of both earthworkers.

The combined work rate is: 1 meter per hour + 1 meter per hour = 2 meters per hour

Now, we can use the combined work rate to determine how much work the earthworkers can complete in 5 hours.

The total work completed in 5 hours is: 2 meters per hour * 5 hours = 10 meters

Therefore, the two earthworkers can dig 10 meters of trench in 5 hours.

Conclusion:

The two earthworkers, with their combined work rate, can dig 10 meters of trench in 5 hours.
