Correct answer: C
Key insight: compute the time spent at each speed, then multiply each time by its speed to get distances and add them.
Calculate the time spent at the first speed: 3/8 of 24 hours = 9 hours. Remaining time = 24 − 9 = 15 hours.
Distance covered at 22 km/h for 9 hours = 22 × 9 = 198 km.
Distance covered at 20 km/h for 15 hours = 20 × 15 = 300 km.
Total journey = 198 + 300 = 498 km.
