Question 1108671
<pre>Use the worker-time-job formula, which is:

{{{(W[1]T[1])/J[1]}}}{{{""=""}}}{{{(W[2]T[2])/J[2]}}}

where

W<sub>1</sub> = the number of workers in the first situation.
T<sub>1</sub> = the number of time units (days in this case) in the first situation.
J<sub>1</sub> = the number of jobs in the first situation.

W<sub>2</sub> = the number of workers in the second situation.
T<sub>2</sub> = the number of time units (days in this case) in the second situation.
J<sub>2</sub> = the number of jobs in the second situation.

W<sub>1</sub> = 10             W<sub>2</sub> = 6
T<sub>1</sub> =  5             T<sub>2</sub> = the unknown quantity
J<sub>1</sub> =  1             J<sub>2</sub> = 1

[Notice that there is only 1 job done in both situations]

{{{(W[1]T[1])/J[1]}}}{{{""=""}}}{{{(W[2]T[2])/J[2]}}}

{{{(10*5[""]^"")/1^""}}}{{{""=""}}}{{{(6*T[2]^"")/1^""}}}

{{{50}}}{{{""=""}}}{{{6T[2]}}}

{{{50/6}}}{{{""=""}}}{{{T[2]}}}

{{{50/6}}}{{{""=""}}}{{{T[2]}}}{{{""=""}}}{{{8&1/3}}}{{{days}}}
