My train was scheduled to leave at 17:48 and to arrive at my destination at 18:25.
However, it started four minutes late, and the journey took twice as long as scheduled.
When did I arrive?
A. 19:39
B. 19:06
C. 19:02
D. 18:29
E. 17:52
B. 19:06
The scheduled leaving time of 17:48 is 12 minutes before 18:00, so the journey time, in minutes, should have been 12 + 25 = 37. So the actual journey time, in minutes, was 2 × 37 = 74, that is 1 hour 14 minutes. Now the train left 4 minutes late, so the leaving time was 17:52. Therefore the arrival time was 1 hour 14 minutes later than 17:52, that is 19:06.
