Correct answer: C
Key idea: at any moment four tyres are in use, so compute total tyre-distance (tyre-km) and then divide that among all five tyres.
Step 1: Compute total tyre-distance = number of tyres in use simultaneously × total distance = 4 × 40000 = 160000 tyre-km.
Step 2: Divide total tyre-distance by total number of tyres = 160000 ÷ 5 = 32000 km per tyre.
Answer: 32000 km per tyre.
