Question

Tom start work in the noon time and complete it in 4 hour 20 minutes how many degrees will the hour hand travel in this duration

Answer 1

Total degree for 12 hours = 360
Degree travelled by hour hand in 1 hour =
$360 \div 12 = 30$
i.e Degree travelled by hour hand in 60 minutes = 30 degree

Therefore, degree travelled by hour hand in 1 minute = 0.5 degree

Total degree moved in 4 hours and 20 minutes = 240+20=260 minutes = 260*0.5=130 degree

Answer is 130 degree
