A rocket is divided into three sections. The top section is one sixth the length of the bottom section . The middle section is one half the length of the bottom section. The total length of the rocket is 180ft. Find the length of the top section.

Respuesta :

Answer:

18 feet long.

Step-by-step explanation:

Let the bottom section be x feet long, then:

x/6 + x/2 + x = 180

Multiply through by 6:

x + 3x + 6x = 1080

10x = 1080

x = 108 feet,

So the top section = 108/6

= 18 feet long.
