My watch gains 5 minutes in every hour. How many degrees the second hand moves in every minute?
-
- 375°
- 380°
- 390°
- 365°
Correct Option: C
Since minute hand gains 5 minutes in every 60 minutes
⇒ second hand gains 5 seconds in every 60 seconds
∴ In every 60 seconds true time, it moves 65 seconds
⇒ 65 × 6° = 390°.
Hence , required answer will be 390° .
