Answer :
Final answer:
The question deals with the concept of relative speed and time conversion. Kareena's watch is losing 15 minutes per 'watch hour', so when her watch shows 11:00 AM, it's actually 11:30 AM.
Explanation:
The subject of this question is Mathematics, focusing on the concept of relative speed and time conversion. It's a problem that relates real-life scenario to mathematical concept, specifically in terms of how we measure and calculate time.
In this question, Kareena's watch loses 15 minutes every hour. This means for every real-life 60 minutes (an hour), Kareena's watch only registers 45 minutes.
So, when Kareena's watch shows 11:00 AM (which means her watch has counted 120 minutes or 2 hours from 9:00 AM), the correct time will be slightly more than 2 hours as for each 'watch hour' there's a loss of 15 minutes.
To determine the real time, we add up the 'loss time'. As Kareena's watch loses 15 minutes in an hour, in 2 'watch hours', the total lost time will be 30 minutes. So, when Kareena's watch shows 11:00 AM, the actual correct time will be 11:30 AM.
