kifflom [539]

Answer: The width of each flag = 12 cm

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

Step-by-step 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. $5x=20\Rightarrow\ x=\dfrac{20}{5}=4\text{ cm}$

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 = $\dfrac{4}{12}$ hour

Time taken to make 1 flag = $\dfrac{1}{3}$ hour

1 hour = 60 minutes

Time taken to make 1 flag = $\dfrac{1}{3}\times60$ minutes = 20 minutes.

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