Question

You must have heard the story of the hare and tortoise. ‘Good morning, tortoise’ said the hare very slowly, mocking the tortoise of his speed. ‘Why do you talk like that, hare? Is there something wrong with you?’ questioned the tortoise. ‘No, but you talk very slow’ said the hare to the tortoise. And he started laughing. ‘I challenge you to a race’ the hare said to the tortoise. He got out of the pond and shook the water from his shell. The first one to arrive at the apple tree on top of that hill would be the winner. The hare wouldn’t believe that he was challenged by a slow tortoise. And he was not merely a slow tortoise; he was an old tortoise, too. They both started the race from the resting position. The race started at 7.00 pm and the tortoise reached the destination by 9.00 pm .The average speed of the tortoise remained 85 Km/h. When the race began, both accelerated forward. The hare accelerated uniformly at a rate of 1 m/s2 for 5 sec. (4.7 seconds). It then continued at a constant speed for 12.5 sec. (11.9 seconds), before getting tired and slowing down with constant acceleration coming to rest 85 (82) meters from where they started. The tortoise accelerated uniformly for the entire distance, finally catching the hare just as the hare comes to a stop.
