Solution
The problem can be solved by using the concept of relative speed.
Step 1: Find the distance covered when the car is serviced. The formula for distance is speed x time. So, the distance covered = speed x time = 60 kmph x 6 hours = 360 km.
Step 2: Find the time taken to cover the same distance when the car is not serviced. The formula for time is distance/speed. So, the time taken = distance/speed = 360 km / 50 kmph = 7.2 hours.
7.2 hours is equal to 7 hours and 12 minutes.
So, the car will take 7 hours 12 minutes to cover the same distance when not serviced.
