Twelve men take 6 hours to finish a piece of work. After the 12 men have worked for 1 hour, the contractor decides to call in 8
Anna71 [15]
Twelve men take 6 hours to finish a piece of work.
In 1 hour, the 12 men will finish 1/6 of the work
( 1 job ) / ( 6 hrs ) = ( 1/6 of a job ) / ( 1 hr )
-----------------------------------------
That means there is of the job
left to do.
-------------------
If 12 men take 6 hours to finish a piece of work,
1 man will take 12 times as long, to finish the work, so
( 1 job ) / ( 6*12 = 72 hrs ) = rate of working for 1 man, or

-------------------
After 1 hour, there are a total of men working
20 men will work 20 times as fast as 1 man on the
of a job that remains, so
Let = hours for the 20 men to finish the job

Please help me :) please
dangina [55]

Answer:

In bold.

Step-by-step explanation:

6/6 = 9/a

So a = 9.

6/c = a/4.5

6/c = 9/4.5 = 2

So c = 3.

By similar triangles:

d/5 = 6/ (6+6+3)

d/5 = 6/15 = 2/5

So d = 2.

Also by similar triangles

b/5 = 12/15 = 4/5

So b = 4.
