This question was previously asked in
RRB NTPC 2019 CBT 1 Question Paper (8-Mar-2021) (Shift 2)
The correct answer is
1 hour, 51 minutes

To convert 1.85 hours into hours, minutes, and seconds, follow these steps:

Convert Decimal Hours to Hours and Minutes

The given time is 1.85 hours.

  • The whole number part represents the hours: 1 hour.
  • The decimal part needs to be converted into minutes.

Calculate the minutes:

$ 0.85 \text{ hours} \times 60 \frac{\text{minutes}}{\text{hour}} = 51 \text{ minutes} $

So, 1.85 hours is equal to 1 hour and 51 minutes.

Convert Remaining Minutes to Seconds

Since the conversion resulted in exactly 51 minutes with no remaining decimal part, there are 0 seconds.

Therefore, 1.85 hours is 1 hour and 51 minutes.
