Answer:
10
Explanation:
Since we know every 4 hours the vid recieves 12,000 views, we divide 12,000 by 4 to see how many views it recieves in 1 hour. We get 3,000. So 3,000 views every hour. Divide 30,000 by 3,000, to get 10 hours.
12,000 views = 4 hours
=> 30,000 views = 4 * (30000/12000) = 10 hours.
Hence it will take 10 hours.
