If 1 person takes 1 hour to dig 1 post hole, how long will it take 2 people to dig 2 post holes?
1 person takes 1 hour to dig 1 post hole
2 persons take 1 hour to dig 2 post holes ,
doubling the number of people working would double the output in the same time
Makes sense. Thanks
If you have 10 men, they can dig a post hole in 6 minutes, right?
To solve this problem, we can use the concept of ratios. Let's break it down step by step:
1. First, we know that one person can dig one post hole in one hour. This means the rate at which they dig post holes is 1 post hole per 1 hour.
2. Now, we want to find out how long it will take for two people to dig two post holes. Since we have two people, the rate at which they dig will be twice as fast as one person.
3. We can set up a ratio to compare the rates. The ratio for one person is 1 post hole per 1 hour. Since two people are working, their rate will be two times faster, so the ratio for two people is 2 post holes per 1 hour.
4. Now, we can modify the ratio to match the desired outcome, which is two post holes. To do this, we multiply both the number of post holes and the number of hours by 2. The modified ratio becomes 4 post holes per 2 hours.
5. From the modified ratio, we see that two people will take 2 hours to dig two post holes.
Therefore, it will take 2 people 2 hours to dig 2 post holes.
