3 men painting a house takes seven and half days. How long would 5 men take over the same job working at the same rate

Show workings bit by bit

AAAaannndd the bot gets it wrong yet again!

Surely even the bot should realize that more men take less time!!

5x = 3*7.5
x = 4.5

1 man takes 7.5 days

Therefore, 3 men take 7.5 x 3 = 22.5 days

Therefore, 5 men take 22.5 x (5/3) = 37.5 days

Did you know?

Did you know that the number of workers can affect the time it takes to complete a task? Let's use a house painting example to illustrate this. If it takes 3 men to paint a house in 7 and a half days, we can calculate the amount of work done per unit of time. Let's call this the "work rate." First, we need to find the work rate of 3 men. Since it takes them 7.5 days to complete the job, we can divide the total work done by the number of days: Work rate of 3 men = 1 (completed job) / 7.5 (number of days) = 1/7.5 Now, let's determine how long it would take 5 men to complete the same job. We know that their work rate should be the same as the work rate of 3 men, so we can set up a proportion: Work rate of 3 men = Work rate of 5 men 1/7.5 = 1/(x days) (where x represents the number of days needed for 5 men to complete the job) To solve for x, we can cross multiply: 1 * x = 7.5 * 1 x = 7.5 Therefore, it would take 5 men approximately 7 and a half days to paint the house. By increasing the number of workers, the job can be completed in a shorter amount of time.
