Question

Pat has been assigned the job of picking apples from the family orchard. He could do the job alone in 8 hours. He knows that his sister, Patti, could do the job in 7 hours. He begs her to help, and she agrees. How long will both of them take to pick the apples? (Round your answer to the nearest tenth.) @mathmate

Answer 3

Check how long each person does in one hour.
If they work together, add them up.
Then the time required is the reciprocal.
