37. A traveler left his house on Tuesday at 10:00 AM and arrived at his destination on Wednesday at 6:00 PM. He stopped twice for 30 minutes each time to get gas and food. He also stopped for a 4-hour nap on Wednesday. How long did he drive for?
Answer: C
27 hours
The traveler drove for a total of 27 hours after accounting for the stops he made during the journey. The total time from departure to arrival was 32 hours, and after subtracting the time spent on breaks, the driving time is calculated.
A) 28 hours
Option A is incorrect because it suggests that the driving time is longer than the actual duration calculated. When the total travel time of 32 hours is adjusted for the 1 hour spent on gas and food stops and the 4-hour nap, the remaining driving time is not sufficient to reach 28 hours.
B) 32 hours
Option B is incorrect as it represents the total time from departure to arrival, which includes all stops. The driving time must exclude the breaks taken for food, gas, and napping, leading to a driving duration of 27 hours, not the full 32 hours.
C) 27 hours
This is the correct answer. The traveler left at 10:00 AM on Tuesday and arrived at 6:00 PM on Wednesday, amounting to a total of 32 hours. After deducting the 1 hour for stops and the 4-hour nap, the driving time calculates to 27 hours.
D) 15 hours
Option D is incorrect as it significantly underestimates the driving time. Considering the total travel duration and the breaks taken, 15 hours does not reflect the actual driving time, which is calculated to be 27 hours after adjustments.
Conclusion
The correct answer of 27 hours accurately reflects the traveler's effective driving time after accounting for all breaks. All other options either miscalculate the total time or fail to adjust for the necessary stops, confirming that they do not represent the actual driving duration.
