If 20 drops fall in 76 seconds, how long will 8 drops take?

x =30.4 seconds

Step-by-step explanation:

We can use ratios to solve

20 drops           8 drops

 =

76 seconds      x seconds

Using cross products

20x = 8*76

20x =608

Divide each side by 20

20x/20 = 608/20

x =30.4 seconds

30.4 secs = 30secs

Step-by-step explanation:

20 drops fall in 76s

Hence 1 drop is 76/20

Therefore 8 drops would be ;

76/20 × 8 = 30.4 secs
