Today's Lateral Thinking question:1.A person crosses a 600 m long street in 5 minutes. What is his speed in km per hour?
2. A train can travel 50% faster than a car. Both start from point A at the same time and reach point B 75 kms away from A at the same time. On the way, however, the train lost about 12.5 minutes while stopping at the stations. The speed of the car is:
