Correct Answer - Option 1 : 01 hr, 58 min.
Given:
Two times = 40 hours 07 minutes and 38 hours and 09 minutes
Concept:
1 hour = 60 minutes
Calculation:
⇒ 40 hours and 07 minutes = (40 × 60) + 07 = 2400 + 7 = 2407 minutes
⇒ 38 hours and 09 minutes = (38 × 60) + 09 = 2280 + 09 = 2289 minutes
⇒ The required difference = 2407 - 2289 = 118 minutes
⇒ The required difference = 118/60 = 1 hours 58 minutes
∴ The required result will be 1 hours 58 minutes.
