C Correct answer
Explanation

First 2/3 of 18 km = 12 km at 12 km/h = 1 hour (60 mins). Remaining 6 km at 8 km/h = 6/8 hours = 0.75 hours (45 mins). Total time = 60 + 45 = 105 minutes.

AI explanation

For the first two-thirds of the 18 km journey, Aisha travels 12 km at 12 km/hour, taking 1 hour or 60 minutes. For the remaining 6 km, she travels at 8 km/hour, taking 6/8 hours, which is 0.75 hours or 45 minutes. Adding both times gives a total ride time of 105 minutes.
