Working independently, Tina can do a certain job in 12 hours. Working independently, Ann can do the same job in 9 hours. If Tina
Leona [35]

Answer:

Ann would need 3 h to complete the remainder of the Job.

Step-by-step explanation:

Step 1.

The "speed" that each girl has to do the work is determined as:

  • Tina: \frac{1}{12h}, it means that Tina complete one twelveth of the job each hour.
  • Ann: \frac{1}{8h}, it means the Ann completes one eighth of the job each hour.

Step 2.

The amount of work done by Tina in 9 hours, is obtain multiplying by the "speed" calculated in step 1:

Amount of work done= 8 h*\frac{1}{12h} = \frac{2}{3}. It means that <em>Tina completes two thirds of the work in 9 h.</em>

Step 3.

The remaining job is calculated as 1-\frac{2}{3}=\frac{1}{3}. It means that <em>still remains is one third of the job to be completed</em>.

Step 4.

The time required for Ann to complete the job is calculated dividing the remaining of the job by the "speed" of Ann to do the job.

\frac{\frac{1}{3}}{\frac{1}{9h}}=3h. It means that <em>Ann would complete the job in another 3 hours</em>.
