Apply the formula suggested by Reddilavan..

ie: Angle = 30Hr-(11/2)Min

ie: Angle = 30Hr-(11/2)Min

By common sense it is clear that in 20 minutes the minute hand will move 20*6=120degree and the hour hand will move20*(1/2)=10degree.

Clearly min hand will be at 20 and hour hand will be 10degree apart.

Clearly min hand will be at 20 and hour hand will be 10degree apart.

we can convert it in hours as:

20min.=1/3hours

so total hours as 4+1/3=13/3

20min.=1/3hours

so total hours as 4+1/3=13/3

Hi All,

We can write 4 hrs. 20 mins. as 13/3 hrs.

13/3 = 4 and (1/3)hrs

= 4.20 ( Here 1 hour = 60 mins, 1/3 of 60 is equal to 20).

Hope you understand guys. Have a nice day!
