A clock gains five minutes every hour. What will be the angle traversed by the second hand in one minute?

Options

A. a) `360^(@)`
B. b) `360.5^(@)`
C. c) `390^(@)`
D. d) `380^(@)`

Answer

B

Explanation

Each second-space equals `1^(@)`. A clock gains five minutes every hours. It means the clock gains `(5)/(60)` minutes in one minute. `(5)/(60) xx 360= 30`. The second hand will traverse `360.5^(@)` in one minute.
