if it takes 8 men 3 hours to clean a house, how many men would it take to get job done in 2.5 hours
8/3 = x/2.5
Solve for x.
To solve this problem, we can use the concept of man-hours.
Given that 8 men can clean the house in 3 hours, we can calculate the number of man-hours required to complete the job:
8 men * 3 hours = 24 man-hours
Now, to find out how many men would be required to clean the house in 2.5 hours, we need to divide the total man-hours by the time taken:
24 man-hours / 2.5 hours = 9.6 men
Since we cannot have a fraction of a man, we need to round up to the nearest whole number. Therefore, it would take 10 men to clean the house in 2.5 hours.
To determine how many men would be needed to complete the job in 2.5 hours, we can use the concept of man-hours. Man-hours represent the number of hours worked by a single individual.
In this case, we know that it takes 8 men 3 hours to complete the job. Therefore, the total man-hours required to clean the house would be 8 men multiplied by 3 hours, which equals 24 man-hours.
Now, we can calculate the number of men required to complete the job in 2.5 hours. We divide the total man-hours (24) by the desired completion time (2.5), which gives us:
24 man-hours / 2.5 hours = 9.6 men
Since we cannot have a fractional number of men, we need to round the answer up to the nearest whole number. Therefore, it would take 10 men to complete the job in 2.5 hours.
