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?
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:

%28W%5B1%5DT%5B1%5D%29%2FJ%5B1%5D%22%22=%22%22%28W%5B2%5DT%5B2%5D%29%2FJ%5B2%5D

where jobs are orders and

W1 = the number of workers in the first situation.
T1 = the number of time units (hours in this case) in the first situation.
J1 = the number of jobs in the first situation.

W2 = the number of workers in the second situation.
T2 = the number of time units (hours in this case) in the second situation.
J2 = the number of jobs in the second situation.

W1 =  5             W2 = 10    
T1 =  1             T2 = 3
J1 = 35             J2 = the unknown quantity

%28W%5B1%5DT%5B1%5D%29%2FJ%5B1%5D%22%22=%22%22%28W%5B2%5DT%5B2%5D%29%2FJ%5B2%5D

%285%2A1%29%2F35%22%22=%22%22%2810%2A3%29%2FJ%5B2%5D

5%2F35%22%22=%22%2230%2FJ%5B2%5D

5%2F35 reduces to 1%2F7

1%2F7%22%22=%22%2230%2FJ%5B2%5D

Cross-multiply

J2 = 210

Answer: 210 jobs (orders)
