The correct answer is 53 km/h.

**Solution:-**To find the average speed of the train, we need to calculate the total travel time and then use the formula for average speed, which is:

Step 1: Calculate the total travel time

• Departure Time: 29^th November 2022, 20:30 hours
• Arrival Time: 1^st December 2022, 13:00 hours

First, let's break down the travel time by date:

• From 29^th November 20:30 to 30^th November 20:30 = 24 hours
• From 30^th November 20:30 to 1^st December 13:00
• To find the time from 30^th November 20:30 to 1^st December 13:00: 20:30 to midnight (24:00) = 3 hours and 30 minutes (since 24:00 - 20:30 = 3:30)
• Midnight to 13:00 on 1^st December = 13 hours

Total time from 30^th November 20:30 to 1^st December 13:00: 3 hours and 30 minutes+13 hours=16 hours and 30 minutes

Thus, The correct answer is 53 km/h.

The correct answer is 80m exactly South.

Key Points

• The subway is in the North direction, and the house is located before the subway, so it must be in the opposite direction.
• Option 1 (480m exactly North) is incorrect because it assumes that the subway is not in the way and the distance is measured directly North.
• Option 2 (280m North-West) is also incorrect because it assumes that the path taken to reach the school is diagonal rather than going around the subway.
• Option 3 (80m exactly North) is incorrect because it assumes that the house is located after the subway, which is not the case.
• It is important to note that the direction of the highway is not mentioned and does not affect the solution.

Jhoom farming is a traditional agricultural practice commonly followed by the tribal communities living in the hilly regions of Mizoram. This method involves clearing a patch of forested land, burning the vegetation, and using the ash as fertilizer. Crops are then cultivated on this land for a few years until its fertility decreases. Once the soil becomes less productive, the farmers move to a new area, allowing the previous land to regenerate naturally. This shifting cultivation method is deeply rooted in the cultural and subsistence practices of the region's people.

The correct answer is Kite and Eagle.

The correct answer is 38 kilometres.

Key Points

The scale on the map indicates that 1 cm on the map corresponds to 960 m in real life.

⇒So, to find the actual distance between the two places in meters, we simply multiply the measured distance by the scale:

⇒39.8 cm × 960 m/cm = 38,208 meters

⇒ Covert this into kilometers (since 1 km = 1,000 m):

⇒ 38208 m / 1000 = 38.21 km ≈ 38 km

Therefore, the real distance between the two places is approximately 38 kilometers.

The correct answer is Himachal Pradesh
