Answer 1

as the hour hand moves 30 degree s 4 every hour for 5 hours it moves 150 degrees

Answer 2

Answer:

Only using the hour hand time formula

12 hr = 360°. --------(1)

1hr = 30° ---------(2)

1min = 1/2° ------------(3)

so,

as per question

12:00 PM - 5:10pm = 5:10 hours

5 hrs *30° =150° ( by using formula 2). --------(4)

10 min *1/2 = 5° ( by using formula 3). ---------(5)

so adding. eqn (4) +(5)

We get 150°+5°= 155° --- (ANSWER)
