Question

what is the angle between two hands of a cloak when the time in the cloak is 7 pm

Answer 1

When the clock hand is at 6 it will form a 180 degree angle.

There are then 6 division between 6 to 12

so, 180/6=30degree

hence, 180 degree + 30 degree =210 degree

Answer 2

in every minute the minute hand covers 6°
because
total angle is 360°
in 1 hour = 60 minutes

therefore, 360/60= 6°
hour hand covers 360° in 12 hours
hence, 360/12= 30°

now minute hand travelled for 0 minute = 0×6=0
also,
hour hand travelled for 7 hours
therefore, 7×30= 210°
hence at 7pm the clock will show 210°
