A) \[18{}^\circ \]
B) \[6{}^\circ \]
C) \[10{}^\circ \]
D) \[3{}^\circ \]
Correct Answer: D
Solution :
As we know that the second hand covers \[360{}^\circ \] in 1 minute i.e. in 60 seconds. So, the second hand covers \[180{}^\circ \]in \[=\frac{60}{360{}^\circ }\times 180=30\]second Also, we know that the minute hand covers \[6{}^\circ \] in 1 minute i.e 60 second. \[\therefore \] The minute hand covers in \[\frac{\text{60}}{\text{2}}\text{=30}\,\,\text{seconds}\]
