Question

Read the given passage and answer the questions that follow based on the passage and related studied concepts. A bus is moving with a velocity of 50 km/h. The driver sees a child running across the road and he pressed the brakes. The time taken by him to stop the bus in this emergency was 1/10 th of a second. In a second case, another bus was coming on the same road at the same 50 km/h and the driver saw another child crossing the road. He applied the brakes and time taken by him to the emergency was 0.5 sec. Both the buses started moving to their destination after 10 minutes. Bus A moved at 45 km/h while bus B moved at 60 km/h.

Two cars started simultaneously towards each other from towns A and B, which are 480 km apart from each other. The first car started from town A and reached the town B in 8 hours. The second car started from town B and reached the town A in 12 hours. If both the cars moved with uniform velocities without any break, find out when the two cars cross each other after starting and at what distance from the town A?
