What is Group Work?

Working together in a group is referred to as group work. The group could consist of several students, workers, employees, etc. Working in a group can increase the success percentage. You can definitely get the benefits of sharing ideas and insights during group work.
Working together is a way of achieving a required goal accurately and quickly as different persons think differently from others and share their thoughts with each other.

The formula to compute the time taken by two people to complete a task is:

Group work = 1/(1/a + 1/b)


  • a = time taken by person 1 in days or hours to complete a task
  • b = time taken by person 2 in days or hours to complete a task


Find the time taken by two persons to complete a project together if person 1 takes 4 days to complete a task and person 2 takes 7 days.


Step 1: Take the values

Person 1 takes = 4 days

Person 2 takes = 7 days

Step 2: Take the formula and place the values.

Group work = 1/(1/a + 1/b)

= 1/(1/4 + 1/7)

= 1/(0.25 + 0.14)

= 1/0.39

= 2.56

Hence 2 and a half days will be required to complete a project if both work together.
