Show answer & explanation
Correct answer: D
Answer: 32000
Key idea: The car uses four tyres at a time, so the total tyre-distance equals the journey distance multiplied by 4. That total is then shared equally among the five tyres.
Total tyre-distance = 40,000 km × 4 = 160,000 tyre-km.
Distance per tyre = 160,000 tyre-km ÷ 5 tyres = 32,000 km.
Therefore each tyre was used for 32,000 km.
