Answer :

Hour’s hand rotates 360° in = 12 hour = 720 min


Minute’s hand rotates 360° in = 1 hour = 60 min


i) At, 1.40hrs


Time past after 0.00 hrs = 1 hr + 40 min = 100 min


In 100 min hour’s hand rotate =


In 100 minminutes hand rotate =


Difference between the hands,


= 240° - 50°


= 190°


ii) At 2.15 hrs,


Time past after 0.00 hrs = 2 hr + 15 min = 135 min


In 135 min hour’s hand rotate =


In 135 min minute’s hand rotate =


Difference between the hands,


= 90° - 67.5°


= 22.5°
