Answer 2

Calculating the Arrival Time of the Next Train

To calculate the arrival time of the next train, we can follow these steps:

1. Current Time Calculation: - The first train arrived at 5:49:40. - We need to convert this time to seconds for easier calculation.

2. Interval Calculation: - The trains run at an interval of 3 minutes and 30 seconds.

3. Next Train Arrival Time Calculation: - Add the interval to the current time to find the arrival time of the next train.

Let's calculate the arrival time of the next train.

Calculation Steps

1. Current Time Calculation: - Convert the current time to seconds: - 5 hours = 5 * 60 * 60 = 18000 seconds - 49 minutes = 49 * 60 = 2940 seconds - 40 seconds - Total seconds = 18000 + 2940 + 40 = 20980 seconds

2. Interval Calculation: - The interval between trains is 3 minutes and 30 seconds, which is 210 seconds.

3. Next Train Arrival Time Calculation: - Add the interval to the current time: - 20980 seconds + 210 seconds = 21290 seconds

4. Convert Seconds to Time Format: - Convert 21290 seconds back to hours, minutes, and seconds: - Hours = 21290 / 3600 = 5 - Minutes = (21290 % 3600) / 60 = 54 - Seconds = (21290 % 3600) % 60 = 50

Conclusion

The next train will arrive at 5:54:50.
