Two plumbers received a job. At first, one of the plumbers worked alone for 1 hour, and then they worked together for the next 4 hours. After this 40\% of the job was finished. How long would it take each plumber to do the whole job by himself if it is known that it would take the first plumber 5 more hours to finish the job than it would take the second plumber?

Easy sense it was 4 hours and 40 percent we know when he is working every hour it is 10 percent so 40 percent and 5 hours would be 50 percent so 40 + 50=90 and there is ur answer 90 that is how u figure the answer out ur welcome plz give me brainiest only if im right thank you.
