What are total man hours worked?
man hours are the total amount of hours each employee works. For example, 10 men working one 10 hour shift would be 100 man hours.
If a man can do work in 8 hours while a child can do same work in 12 hour then together working they will complete the work in how many hours?
Man does (1/8) job in 1 hour. Child does (1/12) job in 1 hour.Working together, they do (1/8 + 1/12) of the job in 1 hour, or (3/24 + 2/24) = 5/24.(1 job) / (5/24 job per hour) = 24/5 = 4.8 hours = 4hours 48minutes
A man leaves his house and walks for 2 hours After walking in a straight line for two hours he is 10 miles from home Calculate the man's average speed in terms of miles per hour?
Average speed = (delta-X) / (delta-T) = (10 miles) / (2 hours) = 5 miles per hour
If it took 6 men 6 hours to dig 6 holes how long did it take 1 man to dig one hole?
Well, if it took 6 men 6 hours to dig 6 holes, that means each man dug one hole in 6 hours. So, it would take 1 man 6 hours to dig one hole. Math doesn't lie, darling.
How long will it take if a man and a woman do a same task together if man gets 2 hours and woman gets 3 hours to do it separately?
Man does (1/2) of task each hour. Woman does (1/3) of task each hour.Working together, they do (1/2 + 1/3) = 5/6 of task each hour.So it will take 6/5 hour = 1 hour 12minutes to do same task together, thengo off and shower together to practice good hygiene after job well done.
