Show answer & explanation

Correct answer: B

Answer: 16:10 hrs.

Reason:

  1. Convert the interval: 2 (1/2) hours = 2 hours 30 minutes.

  2. Find the previous scheduled departure before 18:00: 18:00 − 2:30 = 15:30.

  3. The announcement said a train left 40 minutes ago, so the announcement time is 40 minutes after the 15:30 departure: 15:30 + 0:40 = 16:10.

Therefore the announcement was made at 16:10 hrs.
