Answer:
It would take 10 days for 2 people working for 5 hours a day to fix a road.
Step-by-step explanation:
Given:
Let the number of people be denoted by 'p'.
Let the number of hours be denoted by 'h'.
Let the number of days be denoted by 'd'.

so we can say that;
Now we can say that.
Job Completed can be calculated by multiplying number of people with number of hours and number of days.
So we can say that;
Job Completed =
Case 2:
We need to find the how many days will it take 2 people working 5 hours a day to fix a road.
So we can say that;
Now we know that;
Job Completed =
Now we know that Job completed would be the same so we can say that;
Dividing both side by 10 we get;
Hence we can say that It would take 10 days for 2 people working for 5 hours a day to fix a road.
