Question: Can you calculate how long it will take for the left clock to reflect the time shown in the right clock ?
Answer: By looking at the diagram, it's very clear that left clock it is quarter to three that means after 15 more minutes the time will be 3 o'clock. Where as in the right clock it is 25 minutes past three, which means that it is 25 minutes after 3 o'clock.
To calculate the time difference, let us keep 3 o'clock as the reference point. So adding 15 minutes (before 3 o'clock) and 25 minutes (after 3 o'clock) will give the exact time difference. Which is 40 minutes. So, it will take 40 more minutes for the left clock to reflect the time shown in the right clock.
