One copy machine copies twice as fast as another.
If both copiers work together, they can finish a particular job in two hours.
How long would it take the slower copier to complete the job working alone?
:
Let t = time for the slower machine to do the job
then
.5t = time required by the faster machine
:
Let the completed job = 1
:
A typical shared work equation
+ = 1
multiply thru by .5t, results:
2 + .5(2) = .5t
3 = .5t
t = 6 hrs the slow one alone
:
:
See if that is true
+ = 1
