C Correct answer
Explanation

Total time from 10:00 a.m. to 11:25 a.m. is 85 minutes. Subtracting 15 minutes waiting gives 70 minutes of travel time (7/6 hours). If one-way distance is d, then d/32 + d/24 = 7/6. Solving: 7d/96 = 7/6, so d = 16 km. Total distance traveled = 16 + 16 = 32 km. The total distance is asked, not one-way.
