I don’t think any of them are correct .. but I may be wrong
7.5 ft because
6/30 = .0005 so then x we factor in equals 7.5 for
If 3 inch....................................20 ft
?inc...........................................57 feet
(57*3)/20=171/20=8.55 inch
9x+14x+4x+90 = 360
27x = 270
x = 10
<F = 14x = 14(10) = 140
