waiting for yur reply.
thank u. Answer by ptaylor(2198) (Show Source):
You can put this solution on YOUR website! Let x=amount of time it would take 20 machines to produce 100 units
Now we know that if five machines can produce 20 units in 10 hours then one machine can produce 4 units in 10 hours or one machine can produce (4/10) units in one hour. Soooo, it takes one machine-hour (one machine working one hour) to produce 4/10 units. Then our equation to solve is:
(4/10)*20*x=100 simplifying we get:
8x=100
x=12 1/2 hours---amount of time it would take 20 machines to produce 100 units
ANOTHER WAY TO LOOK AT THE PROBLEM:
5 machines produce 20 units in 10 hours
5 machines produce 2 units in 1 hour
Then 20 machines produce 8 units in 1 hour
Hope this helps----ptaylor
