1.
An accurate clock shows 8 o'clock in the morning. Through how may degrees will the hour hand rotate when the clock shows 2 o'clock in the afternoon?
Answer: Option
Explanation:
| Angle traced by the hour hand in 6 hours = |  |
360 | x 6 |  |
° | = 180°. |
| 12 |

In 12 min min hand takes 6 degree.
So for 6 hrs it takes ?
(6*60*6)/12 = (3600*6)/3 = 180 deg.
So for 6 hrs it takes ?
(6*60*6)/12 = (3600*6)/3 = 180 deg.

A Clock strikes every hour-once at 1.00, twice at 2.00, and so on. The clock takes 6 seconds to strike 5.00 and 12 seconds to strike 9.00. the time needed to strike 1.00 is negligible. How long does the clock need for all its striking in 24 hours?
a)168 Seconds
b)178 Seconds
c)188 Seconds
d) 198 Seconds
How to solve this question?

Sethil ji you are wrong. A complete rotation means 360 degree. & 2 o 'clock comes its half as in 6 position. So ans is 360/2=180 degree simple.

Rishi. Good solution.

Each hour takes 180 degree to rotate.
That's very simple concept each clock takes a complete rotation to complete an hour. So one complete rotation denotes the angle of 180 degree.

HEY MARAN...HERE IS A ONE MORE METHOD 2 SOLVE DIS...
SEE WE HAVE TO FIND THE DEGREE @ 2p.m.
1 HR=30 DEGREES
SO THE GAP TIME BETWEEN 8a.m. to 2p.m. IS 6 HRS...
SO 6*30=180 DEGRESS...
I HOPE U UNDERSTOOD....

Clock is consider as circle 360 deg
the duration of Time= 6 hrs
total = 12 hrs
calculated deg=time duration*deg/total hrs
=6(360/12)=180
the duration of Time= 6 hrs
total = 12 hrs
calculated deg=time duration*deg/total hrs
=6(360/12)=180
