Question 1037565
.
(a).60 people working 8 hours a day takes 4 days to farm . How long will it take 20 people to do the same farm if they work 15 hours a day?Thank you
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


60*8*4 = 20*15*d.


Find d, the number of days under the question, from this equation.


The equation says that the number of man-hours is the same in both cases.
