To find: The time duration that will take by both to do the job together.

Answer to Problem 46SR
Thetime duration that will take by both to do the job together is
Explanation of Solution
Given:
A worker can do the job in
Another worker can do the job in
Let the time taken by the workers when they work together is
So the work done by both the workers together in
The work done by the first worker in
The work done by the second worker in
So the work done by both the workers together in
So the hours spend by both the worker together to do the job is:
Therefore the time duration that will take by both to do the job together is
