Solution
To determine the time shown on the mirror, we need to understand how the reflection works. When an object is reflected in a mirror, the left side becomes the right side and vice versa.
In this case, if the time on the clock is 7 hours 15 minutes, we need to reverse the positions of the hour and minute hands.
First, let's reverse the hour hand. Since the clock shows 7 hours, the reversed position would be 5 hours.
Next, let's reverse the minute hand. The clock shows 15 minutes, so the reversed position would be 45 minutes.
Therefore, the time shown on the mirror would be 5 hours 45 minutes.
Looking at the given options, the closest match is option d. 4 hours 45 minutes. However, since we reversed the positions, the correct answer would be 5 hours 45 minutes.
