If it takes 5 men 20 hours to brick a house, How long will it take 8 men to do the job if they work at the same rate
Answered by Lee
Each of the 5 men worked 20 hours. What is the total man hours required?
Using that total figure how many hours for 8 men. Obviously it will be less, correct?
Answered by oobleck
8/5 as many men, so 5/8 as much time.
