The angle between the minute hand and the hour hand of a clock when the time is 4.20, is:
Answer : Option B
Explanation :
Angle traced by hour hand in \( \frac { 13 } { 3 }\)hrs=[\( \frac { 360 } {1 2 }\)x\(\frac { 13 } { 3 }]^o \)=130°.
Angle traced by min. hand in 20 min. =[\( \frac { 360 } {1 2 }\)x\( 20]^o\)= 120°.
Required angle = (130 - 120)° = 10°
