Answer:
250
Explanation:
Total length of fence = 3,000 ft
additional info
for every 48 ft of fence, there are 4 posts
4 post covers 48 ft of fence
1 post will cover 48/4 ft of fence (dividing both side with four)(48/4 = 12)
=> 1 post will cover 12 ft of fence
Given that the Total length of fence is 3,000 ft
no of post required to cover total length of fence will be
= Total length of fence / length of fence 1 post covers
substituting value of Total length of fence(3000 ft)
and length of fence 1 post covers (12 ft)
we have
no of post required to cover total length of fence will be
= 3000/12
= 250 ------Answer
