Answer:
Simon takes approximately 13.76 hours to complete the job alone.
Step-by-step explanation:
We are given the following in the question:
Kamila can do a job in 26 hours
So, part of work done by Kamila in 1 hour =
Simon and Kamila working together can do the same job in 9 hours .
So, (Simon and Kamila)'s 1 hour work =
So, Simon's 1 hour work =
So,
Simon can do part of work in hour = 1
Time taken by Simon to complete the job alone =
Thus, Simon takes approximately 13.76 hours to complete the job alone.
