Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

India has a single time zone (IST, UTC+5:30), but due to its east-west extent, the sun rises about 2 hours earlier in the east than in the west. Tirap in Arunachal Pradesh is in the far east, while Kandla in Gujarat is in the west. If sun rises at 5:00 AM in Tirap, it would rise around 7:00 AM in Kandla - approximately 2 hours later due to the longitude difference of about 20-25 degrees between these locations.

Multiple choice general knowledge

At noon and midnight the hour and minute hands are exactly coincident with each other. How many other times between noon and midnight do the hour and minute hands cross

  1. 8

  2. 10

  3. 9

  4. 11
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The hour and minute hands coincide 11 times in every 12-hour period (approximately every 1 hour and 5.5 minutes). Between noon and midnight, excluding the exact endpoints of noon and midnight, they coincide 10 times - at approximately 1:05, 2:10, 3:16, 4:21, 5:27, 6:32, 7:38, 8:43, 9:49, and 10:54. Option A (8) and C (9) underestimate, while D (11) would be correct only if counting the endpoints.

Lowell started his homework at 5:00pm. He spent 45 minutes on English, 35 minutes on math, and 1 hour 15 minutes on history. At what time did he finish all his homework?

  1. 7.35 pm

  2. 7.20 pm

  3. 6.35 pm

  4. 6.20 pm
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Total time spent is 45 min (English) + 35 min (Math) + 75 min (History) = 155 minutes. 155 minutes is 2 hours and 35 minutes. Adding 2:35 to the 5:00 PM start time results in a finish time of 7:35 PM.

  4. 2.0
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

India's longitudinal extent from east to west is approximately 30 degrees (from 68°7'E to 97°25'E), which theoretically spans about 2 hours. However, India uses a single time zone (IST +5:30) for the entire country. The question asks about the natural time difference based on longitude, not the political timekeeping system.

Russia currently has 11 time zones (reduced from 11 to 9 in 2010, then partially restored to 11 in 2014). The option of 12 represents historically accurate information or common approximation. Russia spans multiple time zones due to its vast geographical expanse from Eastern Europe to the Pacific.

If the hour hand on a clock moves 1/60th of a degree every minute then how many degrees will the hour hand move in one hour?

  1. 360 degrees

  2. 60 degrees

  3. 1 degree

  4. 120 degree
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

To solve this question, the user needs to know the number of minutes in an hour and the angle moved by the hour hand in one minute.

The hour hand of a clock completes one full revolution of 360 degrees in 12 hours, or 720 minutes. Thus, in one minute, the hour hand moves 360/720 = 1/2 of a degree.

To find the answer, we need to multiply the number of degrees moved by the hour hand in one minute by the number of minutes in an hour:

1/2 * 60 = 30

Therefore, the hour hand on the clock moves 30 degrees in one hour.

Now let's go through each option and explain why it is right or wrong:

A. 360 degrees: This option is incorrect. The hour hand of a clock does not move 360 degrees in one hour, as it only completes 1/12th of a revolution.

B. 60 degrees: This option is incorrect. The minute hand of a clock moves 60 degrees in one hour, but the hour hand moves much less.

C. 1 degree: This option is incorrect. The hour hand moves much more than 1 degree in one hour.

D. 120 degrees: This option is incorrect. The hour hand moves 30 degrees in one hour, not 120 degrees.

Therefore, The Answer is: C. 1 degree.

Explanation

Australia spans three time zones: Australian Western Standard Time (AWST, UTC+8), Australian Central Standard Time (ACST, UTC+9:30), and Australian Eastern Standard Time (AEST, UTC+10). Some territories use half-hour offsets. This is due to Australia's large east-west geographic extent.
