Final answer:
To determine the time the train left, we need to add the delay of 47 minutes to the scheduled departure time of 4:39 pm. The train left at 5:26 pm.
Step-by-step explanation:
To determine the time the train left, we need to add the delay of 47 minutes to the scheduled departure time of 4:39 pm.
First, let's convert the time to a 24-hour format. In a 24-hour format, 4:39 pm becomes 16:39.
Adding 47 minutes to 16:39, we get:
16:39 + 47 minutes = 17:26.
Therefore, the train left at 17:26, or 5:26 pm.
