Work it exactly like the other one with Wilda and Karla.
Juan takes 15 hours to do a job ... he does 1/15 of it in an hour. His father can do it in 6 hours ... he does 1/6 of it in an hour.
Juan works alone for 4.5 hours. In that time, he does 4.5/15 = 0.3 of the job. When his father joins him, there's only 0.7 of it to finish.
Working together, they do (1/15 + 1/6) = (2/30 + 5/30) = 7/30 of the job each hour.
How many times do they have to do 7/30 of the job in order to finish the 7/10 of it that remains ? That will be the number of hours they need.
(7/10) / (7/30) = 7/10 x 30/7 = 3 hours .
Then they can knock off while it's still daylight, and go for a swim.
Juan works alone for 4.5 hours and completes 30% of the job. When his father joins him, they finish the remaining 70% in 3 hours together. Thus, the total time taken by both Juan and his father working together to finish the job is 3 hours.
