Question 122894
x represents the length of the first
y represents the length of the second
z represents the length of the third

so x+y+z=48

the second piece is twice as long as the first then y=2x
the third piece in 3 times as long as the first then z=3x

then x+2x+3x=48 so 6x=48 so x=8

1st=x=8
2nd=y=16
3rd=z=24
