Category: Miscellaneous Indian Gk

Hint: Add the travel time to the departure time.

Correct Answer: C) 5: 10 PM.

Exam Relevance: Common Entrance Exams, Competitive Exams

Difficulty: Easy

Explanations:

To determine the arrival time of a train that departs at 9:10 AM and travels for 8 hours, you need to add the travel duration to the departure time. This involves adding the hours and minutes separately and converting the result to the correct time format.

First, let's break down the departure time and the travel duration:

Departure time: 9:10 AM

Travel duration: 8 hours

Adding 8 hours to 9:10 AM involves the following steps:

1. Add the hours: 9 AM + 8 hours = 17:00 (in 24-hour format)

2. Add the minutes: 10 minutes remain the same

So, 9:10 AM + 8 hours = 17:10 (in 24-hour format)

To convert 17:10 to the 12-hour format, we subtract 12 from 17:

17:10 - 12:00 = 5:10 PM

Therefore, the train arrives at 5:10 PM.

It is important to note that when adding hours to a time, you need to consider the 12-hour cycle of the clock. If the sum of the hours exceeds 12, you subtract 12 to convert it to the 12-hour format. In this case, 17:10 in 24-hour format is equivalent to 5:10 PM in 12-hour format.

Common mistakes include forgetting to convert the time to the correct format after adding the hours and minutes, or misunderstanding the 24-hour clock system and incorrectly converting AM/PM times. Always ensure that you correctly account for the 12-hour cycle when converting times.

Option Analysis:

Option A: This option is incorrect because adding 8 hours to 9:10 AM results in a time in the afternoon, not in the morning. The time 5:10 AM is too early and does not account for the 8-hour journey.
Option B: This option is incorrect because adding 8 hours to 9:10 AM results in a time in the afternoon, not in the morning. The time 10:05 AM is also too early and does not account for the 8-hour journey.
Option C: This option is correct because adding 8 hours to 9:10 AM results in 5:10 PM. The train departs at 9:10 AM and travels for 8 hours, arriving at 5:10 PM.
Option D: This option is incorrect because adding 8 hours to 9:10 AM results in 5:10 PM, not 4:10 PM. The time 4:10 PM is one hour too early and does not account for the full 8-hour journey.

Mnemonic: Remember to add the hours and minutes separately.
