A man owns a clock that loses 10 minutes every hour. He sets it correctly at noon. What time will the clock display after 6 real hours?

Hint
The clock loses 60 minutes over six hours.

Answer

6:00 PM.

Explanation

The clock loses 10 minutes per real hour. In 6 hours it loses 60 minutes, so when the real time is 6 PM, the clock displays 5 PM.

Step-by-Step Solution

Loss = 10×6 = 60 minutes.
Real time = 6:00 PM.
Clock time = 5:00 PM.
