The London to Calcutta bus journey distance is approximately how many kilometers?

• A. 12,000 km
• B. 5,000 km
• C. 30,000 km
• D. 20,300 km

Answer: (D)

Distance on a long road trip is about following the actual route and adding up the kilometers, not just the straight-line distance between cities. A practical London to Kolkata bus route would span multiple countries, traveling across Europe and into Asia before reaching India, so the road mileage climbs into the twenty-thousand-kilometer range. About 20,300 km is a reasonable estimate for that kind of continental trip. The other options don’t fit: 12,000 km would be closer to a direct or shorter route and omits many road segments; 5,000 km is far too short for crossing continents; 30,000 km would be more than a complete circumnavigation and not necessary for this route. So the best approximation for a road journey is around 20,300 kilometers.
