It was raining outside and making a rhythmic dripping sound that slightly amused Samatha. She counted 6 drips every 20 seconds. It is10:00pm at night. At this rate,how many drips will Samatha hear until midnight (counting the drips at 10:00pm and midnight)?
10-10:59 - 1 hour
11-11:59 - 1 hour
12 - 1 minute
2hrs 1 minute = 121 minutes
121 minutes*60 seconds per minute = 7260 seconds
7260 * (6/20) = 2178 drips
