So in this question, according to your company's safety regulations, the distance from the base of a ladder to a wall that it leans against should be at least one -fourth of the ladder's total length.
00:13
You are given a 20 -foot ladder to place against a wall at a job site.
00:17
If you follow the company's regulation, what is the maximum distance of the wall that the ladder will reach to the nearest 10th? so let's start by drawing a picture.
00:29
So we have this wall, and then we have this ladder leaning against the wall.
00:39
And they say that the length of the ladder is 20 feet.
00:45
Now, the distance from the base of the ladder to the wall should be at least one -fourth of the ladder's total length.
00:58
So 1 fourth times 20 is 5.
01:05
So this distance here is going to be 5.
01:11
And i want to know what is this maximum distance.
01:16
I'll call that distance y up the wall that the latter will reach to the nearest 10th...
