Tanya's clock loses 5 minutes every hour. Guests will arrive at Tanya's place at noon. It is currently 6 a.m. What time should she set the clock hands to so that the clock shows the correct time at noon?
Noon will arrive in 6 hours. During this time, Tanya's faulty watch will fall behind by $5 \cdot 6=30$ minutes. To ensure the watch shows the correct time at noon, at 6 AM, one should add an extra 30 minutes, that is, set the watch to $6: 30$.

## Answer

At $6: 30$.
