Question 1066816
2 workers pack 120 phones in 6 hours. how long will 5 workers to pack 400 phones if they work at the same rate?
-----
time is directly related to # of phones and indirectly 
related to # of workers::
t = k*p/w
-------------------
Solve for "k" using "2 workers pack 120 phones in 6 hours".
6 = k*120/2
----
k = 1/10
------------
Equation:
t = (1/10)*p/w
-------
"how long will 5 workers to pack 400 phones if they work at the same rate?"
t = (1/10)*400/5
----
time = 8 hours
---------------
