The difference of the heights is 65-45=20 feet, and the length of the ravine is 21 feet. By the Pythagorean Theorem, the length of the zipline is sqrt(20^2+21^2)=sqrt(841)=29.
The largest number of different whole numbers that can be on Zoltan's list is 999
<h3>How to determine the largest number?</h3>
The condition is given as:
Number = 1/3 of another number
Or
Number = 3 times another number
This means that the list consists of multiples of 3
The largest multiple of 3 less than 1000 is 999
Hence, the largest number of different whole numbers that can be on Zoltan's list is 999
