Answer:

1 1/5 hours

Explanation:

Tiana takes two hours to complete a task

Elena takes three hours to complete the same task

How long will it take for Tiana and elena to complete the task if they work together

This is calculated as:

1/2+ 1/3 = 1/T

Lowest common denominator = 6

Hence:

3 + 2/6 = 1/T

5/6 = 1/T

Cross Multiply

5T = 6

T = 6/5

T = 1 1/5 hours
