Build a timeline with 8 range of years. Ex 1446-1500, 1700-1800 etc. In each time zones write 4 characteristics of the music for guitar at that time, and 1 famous performer or composer for each time.

2 2/3 hours

Step-by-step explanation:

Before it was 5 hours for 1 guitar, or 5 hours/guitar

Now it is 7 guitars in 3 hours or 7/3 hours/guitar

7/3 = 2 1/3

5 hours - 2 1/3 hours = 15/3 hours - 7/3 hours = 8/3 hours = 2 2/3 hours

The reduced the time it takes to build 1 guitar by 2 2/3 hours.
