a 480m pipe is cut into three pieces the second piece is three times as long as the first. the third piece is four times as long as the second how long is each piece?
***
let x=length of 1st piece
3x=length of 2nd piece
4*3x=12x=length of 3rd piece
..
x+3x+12x=480
16x=480
x=30   
3x=90
12x=360
length of 1st piece =30m
length of 2nd piece=90m
length of 3rd piece=360m
