30 minutes. Odometer is a device that records the distance traveled by the car. Therefore as the car's odometer changed its readings there is difference of 30km. If the speed of the car is 60km/h.Then as per unitary method it wil cover 30 km in 30 mins.
60km in 1hr or 60mins
1km in (60/60)mins
30km in(60/60) *30
