Answer:
6.55 meters each day
Step-by-step explanation:
You know that in the end the fence must be 42.6 meters long.
On Monday & Tuesday, he installed 22.95 meters of fence. (We know this because 13.45 + 9.5 = 22.95).
So, how much is left? You find that by subtracting 22.95 from 42.6.
42.6-22.95 = 19.65 meters
There are 3 days left of fencing, and these days he will install equal lengths, so you can divide 19.65 meters by 3 days.
19.65 / 3 = 6.55 meters of fence per day
