Question

It takes 10 road workers 5 days to complete a road repair when working 2 hours a day. Working at the same pace, how many days will it take 2 people working 5 hours a day to finish it?

Answer 1

10 days.

Explanation:

10 workers working 5 *2 = 10 hours do the job.

So 1 worker will take 100 hours to do the job.

2 workers will take 50 hours.

- so they will take 10 * 5 days.

Answer 2

Answer: 10 days

Explanation:

The total number of hours worked is 10 x 2 x 5 which is 10 hours

So two people working 5 hours is 2 x 5 which is 10 hours.

So to get 100 hours they have to work 10 days
