Question

a
How many hours would it take to fill the order if the number of working machines decreased by factor of 2?

Answer 1

Answer:

11 hours

Step-by-step explanation:

The number of machines working in the factory = 6 machines

Decreasing it by a factor of 2 =

6 ÷ 2 = 3 machines.

Hence:

If 6 machines complete a big order = 22 hours

3 machines = x hours

Cross Multiply

6 machines × x hours = 22 hours × 3 machines

x hours = 22 hours × 3/6

= 66/6

x = 11 hours

Therefoee, it would take 11 hours to fill the order if the number of working machines decreased by factor of 2.
