    Special number
    There are random numbers generators. It's a well known fact. But a less known fact is that every random number generator has its inventory imp. Its job is to supervisor the generated numbers so that all numbers are generated equally.   Our imp's name is Igor and he is working for such a number generator that can generate up to ten digit numbers, while no such number with all same digits can be generated (they don't look random enough).   His job is to write down every generated number (right aligned) and its inventory number. The inventory number says, how many digits of each were used in the random number. In the example you can see the generated random number 7970123 as well as its inventory number.   Yesterday, a strange situation happened. After Igor wrote down another inventory number that day, he found out, it was completely same as the random number it belongs to!   What number was it?

    Cars
      Bill and William have decided to pull out his old cars from garage, in order to try how fast still they are. They did everything in form of contest, so they have dealed to stand in the start line and do a certain distance with cars in full throttle. Of course win that one, who reach the finish line first. When they reached the finish line they found out, that the car of Bill is 1,2 times faster, than the car of William. William has reached the finish line about 1 minute and 30 seconds later, than Bill. The bill´s car has reached in this given distance 60km/h speed in average. The question is: How long have to be this distance that they have passed, if we know the above said data? Enter the result in kilometers.
