Question 898210
if it takes 5 people to make 35 orders in 1 hour how many orders does it take 10
people to make in 3 hours?
<pre>
Since 

      5 people can make 35 orders in 1 hour

therefore

     10 people can make 70 orders in 1 hour

and therefore

     10 people can make 210 orders in 3 hours.

Second way:

Use the worker-time-job formula, which is:

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

where jobs are orders and

W<sub>1</sub> = the number of workers in the first situation.
T<sub>1</sub> = the number of time units (hours 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 (hours in this case) in the second situation.
J<sub>2</sub> = the number of jobs in the second situation.

W<sub>1</sub> =  5             W<sub>2</sub> = 10    
T<sub>1</sub> =  1             T<sub>2</sub> = 3
J<sub>1</sub> = 35             J<sub>2</sub> = the unknown quantity

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

{{{(5*1)/35}}}{{{""=""}}}{{{(10*3)/J[2]}}}

{{{5/35}}}{{{""=""}}}{{{30/J[2]}}}

{{{5/35}}} reduces to {{{1/7}}}

{{{1/7}}}{{{""=""}}}{{{30/J[2]}}}

Cross-multiply

J<sub>2</sub> = 210

Answer: 210 jobs (orders)
