At what angle the hands of a clock are inclined at 15 minutes past 5?

Answer: Option

Explanation:

Angle traced by hour hand in | 21 | hrs = | 360 | x | 21 | ° | = | 157 | 1 | ° | ||

4 | 12 | 4 | 2 |

Angle traced by min. hand in 15 min. = | 360 | x 15 | ° | = 90°. | ||

60 |

Required angle = | 157 | 1 | ° | - 90° = 67 | 1 | ° | ||

Use the formula.

=(11/2*min-30*hour),

11/2*15-30*5,

165/2-150,

135/2=67.5.

=(11/2*min-30*hour),

11/2*15-30*5,

165/2-150,

135/2=67.5.

@ALL.

Multiply it with 6(360/60) and for hrs multiply it by 30 (360/12) here in this problem they said 15 min past 5.

So, 5.15 take 15 min alone and multiply it with 6 gives 90 and then take 5.15 fully convert that 15min into hrs so it 5(1/4) in mixed fraction by converting into proper fraction we have 21/4 then multiply it with 30 gives 157.5 subtract 90 from it gives answer 67.5.

Best way to find the angle between hr and min hand is 30H - 5.5M.

Here We have to find angle between 5:15.

For 5 hours = 5 * 30 = 150,

for 15 min = 15 * 5.5 = 82.5,

Therefore 150 - 82.5 = 67.5.

For 5 hours = 5 * 30 = 150,

for 15 min = 15 * 5.5 = 82.5,

Therefore 150 - 82.5 = 67.5.

They given what angle hands of a clock k 5hrs 15min.

Actually 60min = 30degree.

1min = 1/2degree.

So what is the degree of 15min?

So 15/2 = 7.5.

We add 60min in 7.5 degrees.

Then, the answer is 67.5.

Actually 60min = 30degree.

1min = 1/2degree.

So what is the degree of 15min?

So 15/2 = 7.5.

We add 60min in 7.5 degrees.

Then, the answer is 67.5.

@Neha.

How can you multiply 150 degree in place of 5? By formula its wrong.

Please explain that.

30 * 150 - 11/2 * 15 = 67.5.

Answer is very simple.

Difference between the hour hand and minute hand is 60 deg but for every minute hour hand will move by 1/2deg and for 15 min hour hand is moved by 7.5 deg so total is 60+7.5 = 67.5 deg.

Difference between the hour hand and minute hand is 60 deg but for every minute hour hand will move by 1/2deg and for 15 min hour hand is moved by 7.5 deg so total is 60+7.5 = 67.5 deg.
