Answer:
The required number of ropes is 9.
Step-by-step explanation:
The length of rope is 65 ft.
The distance to the base of cliff was 585 ft.
Let the number of ropes or same lengths did it take climber to reach descent be x.
[tex]65\times x=585[/tex]
Divide both sides of 65.
[tex]x=\frac{585}{65}[/tex]
[tex]x=9[/tex]
Therefore the required number of ropes is 9.
