Question

3 hours 20 minutes 20 seconds multiply by 9​

Answer 1

Step-by-step explanation:

20 seconds* 9 = 180 seconds= 3 minutes

20 minutes* 9 = 180 minutes= 3 hours

3 hours*9 = 27 hours

27 hrs + 3 hrs + 3 minutes=

30 hours 3 minutes

Answer 2

3 hrs = 3×60= 180min

180+20=200min

200min=200×60=12000sec

multiply by 9=12000×9=108000sec
