You can put this solution on YOUR website! 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:
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
reduces to
Cross-multiply
J2 = 210
Answer: 210 jobs (orders)
