Fence post are placed 3m apart from each other. How many posts will be placed over a distance of 45m?
16
45/3 = 15
unless they form a closed area, where the 1st and last posts are the same. Then it's back to 15.
To find out how many fence posts will be placed over a distance of 45m, we need to divide the total distance by the distance between each post, which is 3m.
The formula to calculate the number of posts is:
Number of posts = Total distance / Distance between each post
Plugging in the values, we get:
Number of posts = 45m / 3m
Simplifying the expression, we have:
Number of posts = 15
Therefore, over a distance of 45m, you would need to place 15 fence posts.
