Brain Teaser-1

  QUESTION- A Ferrari is traveling at 30 miles per hour on a head-on collision course with a Maserati, which is being driven at a leisurely 20 miles per hour. When the two cars are exactly 50 miles apart, a very fast fly leaves the front fender of the Ferrari and travels towards the Maserati at 100 miles per hour. When it reaches the Maserati, it instantly reverses direction and flies back to the Ferrari and continues winging back and forth between the rapidly approaching cars. At the moment the two cars collide, what is the total distance the fly has covered?

SOLUTION-At first glance it may seem that a horrendous calculation is necessary to solve this: the sum of an infinite series of numbers that get smaller and smaller as the cars approach each other. But if you focus on time rather than distance, a solution is easy. The cars are 50 miles apart and traveling towards each other at a combined speed of 50 miles per hour, so they will meet in one hour. In that hour, a fly that flies at 100 miles per hour will naturally travel 100 miles.

Laugh Out Loud-1

A man approaches a hospital which has developed anew procedure for brain transplant and asks if he could get one to get rid of a brain disease.
                   "Sure" says the doctor"Two fresh brains have arrived this morning after an accident-one of a bus driver and one of a scientist.The brain of the bus driver costs Rs 3.5 lakhs while that of the scientist cost only Rs 5000."
                The puzzled patients asks,"Why is the scientist's brain so cheap?"
               The doctor replies,"That's because its been used often."

Why Are Goals Important?

On the best sunny day, the most powerful magnifying glass will not light paper if you keep moving the glass. But if you focus and hold it, the paper will light up. That is the power of concentration.
A man was traveling and stopped at an intersection. He asked an elderly man, "Where does this road take me?" The elderly person asked, "Where do you want to go?" The man replied, "I don't know." The elderly person said, "Then take any road. What difference does it make?"
How true. When we don't know where we are going, any road will take us there.
Suppose you have all the football eleven players, enthusiastically ready to play the game, all charged up, and then someone took the goal post away. What would happen to the game? There is nothing left. How do you keep score? How do you know you have arrived?
Enthusiasm without direction is like wildfire and leads to frustration. Goals give a sense of direction. Would you sit in a train or a plane without knowing where it was going? The obvious answer is no. Then why do people go through life without having any goals?


It Is The Little Thing That Makes a Great Difference

There was a man taking a morning walk at beach. He saw that along with the morning tide came hundreds of starfish and when the tide receded, they were left behind and with the morning sun rays, they would die. The tide was fresh and the starfish were alive. The man took a few steps, picked one and threw it into the water. He did that repeatedly. Right behind him there was another person who couldn't understand what this man was doing. He caught up with him and asked, "What are you doing? There are hundreds of starfish. How many can you help? What difference does it make?" This man did not reply, took two more steps, picked up another one, threw it into the water, and said, "It makes a difference to this one."

What difference are we making? Big or small, it does not matter. If everyone made a small difference, we'd end up with a big difference, wouldn't we?

BRTS-AHMDABAD

Unlike its Delhi twin, Ahmedabad's Colombia-inspired Bus Rapid Transport System (BRTS) is its pride. It is nearly 30 km long and will grow to 90 km in two years. It won the prestigious 2010 Sustainable Transport Award this year from the Transportation Research Board in Washington. From being clouded by doubt on whether bus rapid transit, which works well in Latin American cities, would be workable in Indian conditions, Ahmedabad's BRTS, which moves 70,000 passengers daily, is on its way to being a model for developing countries. In contrast, the Delhi government is struggling to keep its 5.8-km BRTS from absolute chaos.
How did they do it? For the first three months, the Ahmedabad Municipal Corporation (AMC) ran its BRTS free; then made design changes based on commuter feedback, such as longer buses. During the first three months of the trial run last year, the AMC picked up special opinion makers-students, professors and teachers, journalists, top industrialists of Gujarat-and gave them free rides to seek suggestions. Most were used. The way the lanes have been drawn, the bus stands designed and the manner in which the system is managed by a computerised traffic management and signal control system from a chamber in the AMC office is proof of its success. The broad roads of Ahmedabad have also helped. Ahmedabad Municipal Commissioner I.P. Gautam says, "We gave the people a sense of ownership."
According to the 2008 DIMTS (Delhi Integrated Multi-modal Transit System) survey on the BRTS, most respondents are displeased with the existing public transportation system and prefer to use private vehicles; the reason-an unreliable bus system. The commute times for private vehicles is a minimum of 45 minutes. Sheila Dikshit's government describes the BRTS as a huge success, but it still takes 20-30 minutes to traverse the one km between the Chirag Dilli and Pushp Vihar crossings. Delhi Police traffic bosses complain that they are not in charge of regulating traffic. Replicating the Ahmedabad success looks unlikely in Delhi.
