By looking in a mirror, it appears that it is 3:30 in the clock. Determine the real time at that instant moment?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → 8:30
A mirror reverses left and right, so each hand appears as far on the other side of the 12 as it really is on its own side. The real time and the mirror time therefore add up to 12:00, written as 11:60 when minutes have to be taken away.
Mirror time: 3:30
Real time \(=\) 11:60 \(-\) 3:30 \(=\) 8:30
In the picture the hour hand is blue and the minute hand amber on both clocks: the minute hand at 6 stays where it is, and the hour hand moves from between 3 and 4 to between 8 and 9.
