A train crosses Park Street every forty-five minutes. About 15 minutes ago, one train has crossed Park Street, and the next train will be crossing Park Street by 9.45 am. What is the time now?
Explanation
To solve this problem, we need to calculate the current time based on the train's schedule and the elapsed time since the last crossing.
1. Identify the given variables:
Interval between trains: 45 minutes
Next train arrival: 9:45 am
Last train crossed: 15 minutes ago
2. Determine the time of the last train:
Since the train crosses every 45 minutes, we subtract the interval from the arrival time of the next train:
Time of Last Train=9:45 am−45 minutes=9:00 am
3. Calculate current time:
We know the last train crossed 15 minutes ago. Therefore, we add 15 minutes to the time of the last train:
Current Time=9:00 am+15 minutes=9:15 am
Correct Answer: Option 3 (9.15 am)
