Given Data:
- Speed of the car when not serviced = 50 kmph
- Speed of the car when serviced = 60 kmph
- Time taken to cover a certain distance after servicing = 6 hours

Calculating Distance:
- Let the distance be 'd' km
- When not serviced: Time taken = Distance / Speed = d / 50
- When serviced: Time taken = Distance / Speed = d / 60

Calculating Time taken when not serviced:
- From the given data, we know that the car takes 6 hours to cover the same distance when serviced.
- So, we can set up the equation as follows:
d / 50 = 6
=> d = 50 * 6
=> d = 300 km
- Now, to find the time taken when not serviced:
Time taken = Distance / Speed = 300 / 50 = 6 hours
Therefore, the car will take 6 hours to cover the same distance when not serviced. So, the correct answer is option 'D) 7 hours 12 minutes'.
