If a bird leaves a nest at 20°C in January and arrives in a warmer region where the temperature is 30°C after traveling 300 km, what is the average temperature difference per 100 km?
Answer
3.33
The correct answer is 3.33 — Thus the average temperature difference is 3.33°C per 100 km.
Step-by-step solution
- Compute temperature difference: 30°C - 20°C = 10°C.
- Find difference per km: 10°C ÷ 300 km = 0.0333°C/km.
- Convert to per 100 km: 0.0333°C/km × 100 km = 3.33°C.
- Thus the average temperature difference is 3.33°C per 100 km.
Common mistake: Forgetting to multiply by 100
Concept tested: Temperature change over distance
