The number of hours it will take both the surveyor and apprentice to complete the same job is 15/56 hours.
<h3>Rate of work</h3>
- Hours it takes the experienced surveyor = 7 hours
- Surveyors rate of work = 1/7
- Hours it takes the apprentice = 8 hours
- Apprentice rate of work = 1/8
If the two work together;
Time taken for both to complete the task = Surveyors rate of work + Apprentice rate of work
= 1/8 + 1/7
= (7+8) / 56
= 15/56 hours
Therefore, the number of hours it will take both the surveyor and apprentice to complete the same job is 15/56 hours.
