1.2km distance in 10 minutes
Explanation:
72km/hr ÷ 60 = km/min
1.2 = km/min
1.2x 10minutes = 12km in 10 minutes
it can't be 15km as proved above in 10 minutes the car will reach 12km,
it can't be 10km as the car is running uniform speed without and retardation,
it can't be 18 as the car will travel 1.2x12mims = 14.4km in 12mins
