A car runs at the speed of 60 kms per hour when not serviced and runs at 72 kms/hr. when serviced. After servicing the car covers a certain distance in 12 hours. How much time will the car take to cover the same distance when not serviced?

The distance covered by the serviced car travelling at 72 km/hr for 12 hours is 72 multiplied by 12, resulting in 864 km. To find the time the unserviced car takes to cover this same distance at a speed of 60 km/hr, divide the distance by the speed. Therefore, 864 divided by 60 yields a time of 14.4 hours.
