Clock Sequencing

Take a specially created short test on Clock sequencing:

1. It is 0 hr 0 min at present. How many degrees will the minute hand move by the time it is 2 hr 30 min

a. 720

b. 900

c. 880

d. 450

2. A clock shows the time as 4:00. After hour hand has mover 150 degrees, the time would be

a. 8:00

b. 10:00

c. 7:00

d. 9:00

3. By how many degrees the hour hand moves in one hour

a. 30

b. 15

c. 60

d. 90

4. A clock shows 7 O'clock. by how many degrees will the hour hand rotate when the clock shows 11 O'clock

a. 60

b. 120

c. 150

d. 240

5. When the time in the clock is 3:20 PM. The acute angle between the hour hand and the minute hand is

a. 15

b. 10

c. 18

d. 20

6. In a period of 3 hr 10 min, the needle hand will move over how many degrees

a. 1140

b. 1000

c. 1180

d. 1040

7. When the time in the clock is 4:30 PM the acute angle between the hour hand and the minute hand is

a. 60 degree

b. 45 degree

c. 75 degree

d. 50 degree

8. A clock shows 3:00. By how many degrees the minute hand will rotate when it is 3 hr 2 min

a. 15

b. 2

c. 20

d. 12

9. When the time in the clck is 3:30 PM. What is the exterior angle between the hour hand and the minute hand

a. 285 degree

b. 75 degree

c. 315 degree

d. 15 degree

10. It is 2:00 PMin the clock. By how many degree the hour hand will rotate when it is 2:30 PM

a. 30

b. 45

c. 15

d. 10

Now, How do we arrive at various calculations. Well it is like this:

A- Movement of hour hand:

1. 360 degree in 12 hour

2. 30 degree in 1 hour

3. 15 degree in 1/2 hour

B- Movement of Minute hand:

4. 360 degree in 60 minute

5. 6 degree in 1 minute

When you have to calculate the acute angle between a time say 3:20PM then the movement of hour hand should also be taken into account. The calculation is like this:

If hour hand is exactly at 3 hr and minute hand is at 20 minute then the angle between them will be 30 degree. The movement of hour hand in 20 minutes will be (30 degree in 1 hour or 60 minutes i.e. (30/60)*20 = 10 degrees). So the acute angle is 30 - 10 =20 degree.
