What is the angle between the two hands of a clock when time is 8:30
Read Solution (Total 6)
-
- ans is:= 75 degree
explaination;
hour hand 12hr-360deg
8hr-?
(8*360)/12=240deg
again hour hand 60min-30deg
30min-?
(30*30)/60=15deg
so total hr hand=240+15=255deg
now min hand; 60min-360deg
30min-?
(30*360)/60=180deg
difference will b 255-180=75deg

- angle between hands=|11M-60H|/2
therefore, |11*30-60*8|/2=75 degree

- Use the formula i.e
1/2(60h-11m) // h-hour and m-minute
1/2(60*8-11*30)
1/2(150)

- for 1 minute the hour hand moves by 1/2 degree
so when the minute hand moves from 12 to 6 i.e., 30 minutes, the hour hand moves by 15 degrees
and the degrees between 6 and 7 is = 5 x 6= 30 degrees
so the diffrence between the hands at 8.30 is 45 degrees - 7 years agoHelpfull: Yes(0) No(0)
- 320 as it is 8.30 in the clock it shows the hour hand towards south west and the remaing angle 270+50
