A time value of 3 4/5 hours equals how many hours and minutes?

• A. 3 h 40 min
• B. 3 h 50 min
• C. 3 h 48 min
• D. 4 h 0 min

Answer: (C)

To convert 3 4/5 hours into hours and minutes, take the fractional part and turn it into minutes. The fraction is 4/5 of an hour, and one hour equals 60 minutes, so 60 × 4/5 = 48 minutes. This gives 3 hours and 48 minutes. Since 0.8 hours is 48 minutes, the total is 3.8 hours, which is 3 4/5. The other options correspond to different fractions of an hour (40 minutes = 2/3 hour, 50 minutes = 5/6 hour) or a full extra hour, so they don’t match.
