The ratio of the length to the width the official german flag is 5:3.Sanda is making 12 german flags for a cuiture show. Each flag she makes has a length of 20 centimeters . It takes her 4 hours to make all the flag. What is the width of each flag and the average amount of time it takes sandra to make each flag?

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.

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 = hour

Time taken to make 1 flag = hour

1 hour = 60 minutes

Time taken to make 1 flag = minutes = 20 minutes.

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