Answer:

12.5 hrs

Step-by-step explanation:

 We have given that:  6 painters can paint the fence in 15 hours

To find : In how many hours 5 workers do the job

Solution : 6 workers can paint the fence in = 15 hours

                1 worker can paint the fence in = 15/6  hours

                 5 workers can paint the fence in = 5×15/6 hours

                                                                       =25/2  hours
