Find the angle between the hour hand and the minute hand of a clock when the time is 3:25 ?47.5°49.5°57.5°87.5°
Solution 1
To find the angle between the hour hand and the minute hand of a clock, we can use the following steps:
-
First, calculate the angle made by the hour hand with respect to 12:00 in 60 minutes. The hour hand moves 360° in 12 hours (or 720 minutes). So, in one minute, the hour hand moves 360/720 = 0.5°. At 3:25, the hour hand has moved 25 minutes. So, the angle of the hour hand at 3:25 is 330 (for 3 hours) + 0.525 (for 25 minutes) = 90 + 12.5 = 102.5°.
-
Next, calculate the angle made by the minute hand with respect to 12:00 in 60 minutes. The minute hand moves 360° in 60 minutes. So, in one minute, the minute hand moves 360/60 = 6°. At 3:25, the minute hand has moved 25 minutes. So, the angle of the minute hand at 3:25 is 6*25 = 150°.
-
Finally, subtract the smaller angle from the larger angle to find the angle between the two hands: 150° - 102.5° = 47.5°.
So, the angle between the hour hand and the minute hand at 3:25 is 47.5°.
Solution 2
To find the angle between the hour hand and the minute hand of a clock, we can use the following steps:
-
Calculate the angle covered by the hour hand. The hour hand covers 360 degrees in 12 hours, so it covers 30 degrees in 1 hour. At 3:25, the hour hand has covered 3 hours and 25 minutes, which is 3.42 hours approximately. So, the angle covered by the hour hand = 30 * 3.42 = 102.5 degrees.
-
Calculate the angle covered by the minute hand. The minute hand covers 360 degrees in 60 minutes, so it covers 6 degrees in 1 minute. At 3:25, the minute hand has covered 25 minutes. So, the angle covered by the minute hand = 6 * 25 = 150 degrees.
-
The angle between the hour hand and the minute hand is the absolute difference between the angles covered by the two hands. So, the angle = |150 - 102.5| = 47.5 degrees.
So, the angle between the hour hand and the minute hand when the time is 3:25 is 47.5 degrees.
Solution 3
To find the angle between the hour hand and the minute hand of a clock when the time is 3:25, follow these steps:
-
Calculate the position of the hour hand: At 3 o'clock, the hour hand is at 90 degrees (each hour is 30 degrees, so 3 hours is 330 = 90 degrees). By 3:25, the hour hand has moved further along. Since the hour hand moves 0.5 degrees per minute, it has moved an additional 0.525 = 12.5 degrees. So the total position of the hour hand is 90 + 12.5 = 102.5 degrees.
-
Calculate the position of the minute hand: The minute hand moves 6 degrees per minute (360 degrees divided by 60 minutes), so at 25 minutes past the hour, it is at 6*25 = 150 degrees.
-
Subtract the smaller angle from the larger to find the angle between the two hands: 150 - 102.5 = 47.5 degrees.
So, the angle between the hour hand and the minute hand at 3:25 is 47.5 degrees.
Solution 4
To find the angle between the hour hand and the minute hand of a clock, we can use the following steps:
-
Calculate the position of the hour hand: The hour hand moves 360 degrees in 12 hours. So, it moves 30 degrees in one hour. At 3:25, the hour hand will be in between 3 and 4. So, it will be 3 hours + 25/60 of an hour = 3.4167 hours from 12. Therefore, the position of the hour hand = 3.4167 * 30 = 102.5 degrees from 12.
-
Calculate the position of the minute hand: The minute hand moves 360 degrees in 60 minutes. So, it moves 6 degrees in one minute. At 25 minutes, the position of the minute hand = 25 * 6 = 150 degrees from 12.
-
Subtract the smaller angle from the larger angle to find the angle between the hour hand and the minute hand: 150 - 102.5 = 47.5 degrees.
So, the angle between the hour hand and the minute hand when the time is 3:25 is 47.5 degrees.
Solution 5
To find the angle between the hour hand and the minute hand of a clock, we can use the following steps:
-
First, calculate the angle covered by the hour hand. The hour hand covers 360 degrees in 12 hours, so it covers 30 degrees in one hour. At 3:25, the hour hand has covered 3 hours and 25 minutes, which is 3.42 hours approximately. So, the angle covered by the hour hand is 30 * 3.42 = 102.5 degrees.
-
Next, calculate the angle covered by the minute hand. The minute hand covers 360 degrees in 60 minutes, so it covers 6 degrees in one minute. At 3:25, the minute hand has covered 25 minutes. So, the angle covered by the minute hand is 6 * 25 = 150 degrees.
-
Finally, subtract the smaller angle from the larger angle to find the angle between the two hands. So, the angle between the hour hand and the minute hand at 3:25 is 150 - 102.5 = 47.5 degrees.
So, the correct answer is 47.5°.
Solution 6
To find the angle between the hour hand and the minute hand of a clock, we can use the following steps:
-
Calculate the angle covered by the hour hand. The hour hand covers 360 degrees in 12 hours, so it covers 30 degrees in 1 hour. At 3:25, the hour hand has covered 3 hours and 25 minutes. So, it has covered 330 + 25(30/60) = 97.5 degrees.
-
Calculate the angle covered by the minute hand. The minute hand covers 360 degrees in 60 minutes, so it covers 6 degrees in 1 minute. At 3:25, the minute hand has covered 25 minutes, so it has covered 25*6 = 150 degrees.
-
Subtract the smaller angle from the larger angle to find the angle between the two hands. So, 150 - 97.5 = 52.5 degrees.
So, the angle between the hour hand and the minute hand at 3:25 is 52.5 degrees. However, this option is not available in the choices given. There might be a mistake in the question or the options provided.
