How long will it take to drive 1,710 km at 90 km per hour, if you take a break two-hour break after every five hours.
To calculate the total time, we need to consider both the driving time and the break time.
The driving time can be calculated as the total distance divided by the driving speed:
Driving time = Distance / Speed
Driving time = 1710 km / 90 km/h
Driving time = 19 hours
Now, we need to take into account the breaks. If a break is taken after every 5 hours of driving, and each break lasts for 2 hours, we can divide the total driving time by the duration of each driving cycle (driving time + break time).
Driving cycle duration = Driving time + Break time
Driving cycle duration = 5 hours + 2 hours
Driving cycle duration = 7 hours
The total time can then be calculated by dividing the total distance by the driving cycle duration:
Total time = Distance / Driving cycle duration
Total time = 1710 km / 7 hours
Total time ≈ 244.29 hours
Therefore, it will take approximately 244.29 hours to drive 1,710 km at a speed of 90 km/h, including the 2-hour breaks taken after every 5 hours of driving.
