A car is traveled 600 km in 6 hours. What is he total time in minutes if the driver needs a break 15 minutes each one hour?
The correct answer and explanation is:
Correct Answer:
390 minutes
Explanation:
To find the total time in minutes, including breaks, follow these steps:
- Travel Time Without Breaks:
The car covers 600 kilometers in 6 hours.
So, the basic travel time is 6 hours. - Break Time Per Hour:
The driver takes a 15-minute break for every hour of driving.
Since the trip lasts for 6 hours, the driver takes one 15-minute break after each hour. - Total Number of Breaks:
Breaks are only taken after each full hour of driving, not at the end of the trip.
That means breaks are taken after the 1st, 2nd, 3rd, 4th, and 5th hours.
This results in 5 breaks in total. - Total Break Time:
Each break is 15 minutes, and there are 5 breaks.
So, the total break time is:
15 minutes × 5 = 75 minutes - Total Time in Minutes:
Now, convert the 6 hours of driving time to minutes:
6 hours × 60 minutes/hour = 360 minutes
Add the total break time:
360 minutes + 75 minutes = 435 minutes
Correction:
There is a mistake in the assumption. The car travels for 6 hours in total, meaning this already includes driving plus breaks. But the question seems to ask how long the trip would take in minutes if the driver takes 15-minute breaks per driving hour.
Let’s re-evaluate assuming the 6 hours is pure driving time:
- 6 hours driving = 360 minutes
- 5 breaks (after each hour, except the last) × 15 minutes = 75 minutes
- Total time = 360 + 75 = 435 minutes
Final Answer: 435 minutes
So, the total time taken for the journey, including breaks, is 435 minutes.
