Final answer:
Jill, a hairdresser, takes 17 minutes per haircut and 90 minutes to color a client's hair. This is determined by subtracting the time for a haircut from the total time after lunch and dividing the remaining time by three to get the duration of one coloring service.
Step-by-step explanation:
Jill is a hairdresser who gave 1 haircut in 17 minutes before her lunch and after lunch, she gave 1 haircut and colored the hair of 3 clients in 287 minutes. To solve this, we should first subtract the time taken for one haircut from the total time after lunch to find the total time taken for coloring three clients' hair.
After subtracting 17 minutes for the haircut from 287 minutes, we have 270 minutes left for the 3 colorings. Since each coloring takes the same amount of time, we divide 270 minutes by 3 to find the time taken for one coloring service. Therefore:
- Time for one coloring service: 270 minutes / 3 = 90 minutes.
- Time for one haircut: 17 minutes.
Assuming the amount of time does not vary from client to client, it takes Jill 90 minutes to color a client's hair and 17 minutes to give a haircut.
