Final answer:
The pull strap for the nylon sled is 92 inches long, which is a considerable length for a sled pull strap allowing for comfortable use.
Step-by-step explanation:
The question asks about the length of a pull strap for a nylon sled. If the given measurement of 92 inches is the length, then this is the detail needed. However, there seems to be a reference to a nylon climbing rope which has a stretch of 9 cm, but this detail does not pertain to the length of the sled's pull strap.
In considering the length of the pull strap, one would conclude that 92 inches, which is equivalent to approximately 233.68 centimeters, is quite long for a sled pull strap and should provide ample length for an individual to comfortably pull the sled.
