The Nilgiri Biosphere Reserve covers 5,500 km² and is estimated to contain 8,000 elephants. What is the elephant density per 100 km²? (Round to the nearest whole number)
Answer
145 elephants per 100 km²
The correct answer is 145 elephants per 100 km² — Round to nearest whole number: 145 elephants per 100 km².
Step-by-step solution
- Calculate density per km²: 8000 elephants ÷ 5500 km² = 1.4545 elephants/km².
- Convert density to per 100 km²: 1.4545 × 100 = 145.45.
- Round to nearest whole number: 145 elephants per 100 km².
Common mistake: Multiplying instead of converting density per km² to per 100 km²
Concept tested: Population density calculation
