1. By the information given in the problem above, you have:
- Bottom section=x
- The top section is one-sixth the length of the bottom section.
Top section=x/6
- The middle section is one-half the length of the bottom section.
Middle section=x/2
- The total length of the rocket is 240 ft.
Bottom section+Top section+Middle section=240
x+x/6+x/2=240
2. Then, you have the the bottom section is:
x=144
3. Therefore, the top section is:
Top section=x/6
Top section=144/6
Top section=24 ft
The answer is: 24 ft
