Answer: The width of each flag = 12 cm

The average amount of time it takes Sandra to make each flag = 20 minutes.

Explanation:

Given: The ratio of the length to the width the official german flag is 5:3.

Let length = 5x, width = 3x

Length of each flag = 20 cm

i.e.
5x=20\Rightarrow\ x=(20)/(5)=4\text{ cm}

Then width of each flag = 3 x 4 = 12 cm

i.e. width of each flag = 12 cm

Total time to make 12 flags = 4 hours

Time taken to make 1 flag =
(4)/(12) hour

Time taken to make 1 flag =
(1)/(3) hour

1 hour = 60 minutes

Time taken to make 1 flag =
(1)/(3)*60 minutes = 20 minutes.

Hence, the average amount of time it takes Sandra to make each flag = 20 minutes.
