If it takes 6 men 4 days to dig a hole 3 meters deep, how long with it take 10 men to dig a hole 7
meters deep? round your answer to the nearest whole dayОтветы на вопрос
1) 3 : 4 = 0,75 m 6 men a day
2) 0,75 : 6 = 0,125 m 1 man a day
3) 0,125 × 10 = 1,25 m 10 men a day
4) 7 : 1,25 = 5,6 (days)
5,6 ≈ 6 days
It will take 6 days for 10 men to dig a hole 7 meters/
To solve this problem, we can use the concept of "man-days," which represents the amount of work done by one man in a day.
Given that 6 men can dig a 3-meter deep hole in 4 days, we can calculate the total man-days required for this task:
Total man-days = Number of men * Number of days = 6 men * 4 days = 24 man-days
Now, we need to find out how long it will take 10 men to dig a 7-meter deep hole. Let's calculate the total man-days required for this task as well:
Total man-days = Number of men * Number of days = 10 men * Number of days
Since we have the total man-days required for both tasks, we can set up a proportion to find the number of days needed for 10 men:
6 men * 4 days = 10 men * Number of days
Now, solve for the Number of days:
Number of days = (6 men * 4 days) / 10 men Number of days = 24 days / 10 men Number of days = 2.4 days
Since we want the answer rounded to the nearest whole day, the answer is approximately 2 days. Therefore, it will take 10 men about 2 days to dig a 7-meter deep hole.
