D Correct answer
Explanation

Anna travels 180 km in the first 2 hours 15 minutes (80 km/h * 2.25 h). The remaining distance is 170 km, which she covers at 60 km/h in 2 hours 50 minutes. Adding 5 hours 5 minutes to 5:20 a.m. results in 10:25 a.m.

AI explanation

For the first part of the trip using Distance = Speed * Time, Anna travels 80 km/hr for 2.25 hours (2 hours 15 minutes), covering 180 km. The remaining distance is 350 km - 180 km = 170 km. Traveling this remaining distance at 60 km/hr takes 170/60 hours, which is 2 hours 50 minutes. Adding the two travel times gives a total time of 5 hours 5 minutes, meaning she reaches city A at 10:25 a.m. The result is 10.25 a.m.
