first milestone 16
second milestone 61
third milestone 106
its an observation..ntn like nethn..onli thing i tht ws dat as speed is
uniform so distance traveled per hr is constant..so two milestones with
reverse numbers wil hv difference as 9x-9y ie multiple of 9..also third
milestone wil
(10b+a)-(10a+b)=[(100b+a)or(100a+b)]-(10b+a)... [uniform speed] where a,b
are natural numbers less than 10...
*1st case*
9(b-a)=90b
a=-9b...not acceptable
*2nd case*
9(b-a)=99a-9b
b-a=11a-b
b=6a...acceptable
and only value which abides by the condition a,b are natural numbers less
than 10
@abhishek:
[(100b+a)or(100a+b)]-(10b+a).
how do u know that this no cantains 1 zero??

Let the number on mile stone 1 be XY, so on next milestone number will be
YX.
Now if we see the numbers again then it is possible only when mile stone 3
contains a 3 digit number.
Also, from above points it is clear that YX is greater than XY and X!=0 and
Y!=0 and YX, and the next number is the
I dont get this part of your proof.. :(.
Y-X is a fraction so it's not valid assumption.
