Question 1082891
For safety, a ladder should be at least 1ft from the wall for every 3ft of ladder.
 How far should the bottom of a 10ft ladder be from the wall?
:
Use proportion, let x = distance a 10' ladder should be from the wall
{{{x/10}}} = {{{1/3}}}
Cross multiply
3x = 10*1
x = 10/3
x = 3{{{1/3}}} ft
