<em><u>Answer</u></em>
5 hours
<em><u>Explanation</u></em>
The two working together can finish a job in

Also, working alone, one machine would take one hour longer than the other to complete the same job.
Let the slower machine working alone take x hours. Then the faster machine takes x-1 hours to complete the same task working alone.
Their combined rate in terms of x is

This should be equal to 20/9 hours.

Multiply through by;





Factor to get:


It is not feasible for the slower machine to complete the work alone in 4/9 hours if the two will finish in 20/9 hours.
Therefore the slower finish in 5 hours.

Answer:
The first value of i is 0 and last value of i is 20.
Explanation:
The following are the description of a given loop.
- In this problem, there are two loops one is the internal loop and the other is the external loop
- In the outer loop, the value of " i" is initialized with "0" So the first value is printed 0 in the console.
- For one value of "i" all the inner loop is executed.
- The loop is executed is less equal to 20 that's why the last value of "i" is printed 20 in the console window.
