It takes 8 hours for 5 people to paint a room.
How long would it take 4 people?
It would take them more than 10 hours.
Here's how you do it
5 / 8 = 0.625
0.625 * 4 = 2.5
2.5 * 4 = ?
Multiply 2.5 * 4 in order to get your answer.
To find out how long it would take 4 people to paint the room, we can use the concept of man-hours. Man-hours represent the total amount of work done by one person in one hour.
In this case, we know that it takes 5 people a total of 8 hours to paint the room. Therefore, the total man-hours required is 5 x 8 = 40 man-hours.
Now, to find out how long it would take 4 people to paint the room, we divide the total man-hours by the number of people. In this case, it would be 40 man-hours / 4 people = 10 hours.
Therefore, it would take 4 people a total of 10 hours to paint the room.
What is the term given to the shaped-curve graph
Well, painting a room is no joke, but I'm here to make you smile! If it takes 8 hours for 5 people to paint a room, then it only makes sense that it would take 4 people 10 hours. After all, with one less person, they might need a bit more time to clown around and get the job done!
rate is 40 person hours/ room
(40 p hr/ r)/(4p) = 10 hr/room
