Question

A job calls for clips to be welded at each end of a 1,863' seawall, Clips are also to be welded 18"

apart along the length of the wall. How many clips will be used on this job?

Answer 1

well, the seawall is 1863' long, since a foot has 12 inches that's 1863*12 inches, now if we divide that length by 18, because each clip is going to be 18" away from each other, that gives us

`\cfrac{(1863)(12)}{18}\implies 1242~\qquad \textit{segments of 18`

Now, let's think of each segment beginning with a clip, that makes it 1242 clips and since the seawall must end with a clip, that means 1242 + 1 = 1243 clips total.
