An airplane flies 1200 kilometers per hour, the speed of a train is exactly (1/6) of the speed of the airplane, and the speed of a car is equivalent to (1/4) of the speed of the train. How many kilometers does this car travel per hour?
一架飞机每小时飞1200千米，一列火车的速度正好是飞机速度的(1/6)，而一辆汽车的速度相当于火车速度的(1/4)．这辆汽车每小时行多少千米？
