Answer:
1 1/5 hours
Step-by-step 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
