Explanation

Departure: 8:35 a.m.

Arrival: 3:12 p.m.

Convert both times to 24‑hour format:

- 8:35 a.m. → 08:35

- 3:12 p.m. → 15:12

Difference:

15:12 − 08:35

→ (15 – 8) hours = 6 hours

→ (12 – 35) minutes = –23 minutes

→ Borrow 1 hour → 6 hours → 5 hours 60 minutes

→ 60 – 23 = 37 minutes

Total journey: 6 hours 37 minutes
