mathematics

The formula to use is R= D/T

Let
the distance between sound waves be D,
the speed of sound be s,
the speed of the moving vehicle v,
the time taken between waves to the stationary car T,
and the time taken to the moving car t.

Then imagining the sound waves were stationary and the cars moving between them, the distance will remain constant.
So
D=sT [FOR THE "STATIONARY" CAR] =(s+v)t [FOR THE "MOVING" CAR]
Whence v=s (T-t)/t

...and since s and t are numerically equal, the question becomes arithmetically trivial.

1) How far does sound travel in 28 seconds? 332 m/s x 28 s = 9296m
2) Bhagwat's car covers this distance in 5'32" = 332 seconds
3) speed = distance / time = 9296/332 = 28 m/s

Hey friends,

While advanced mathematics may not be required for programming the thought process of programming and mathematics are very similar. You begin with a base of known things and try to get to someplace new. You cannot skip steps. If you do skip steps, then you are required to fill in the blanks. It's a critical thought process that makes the two incredibly similar.

Also, mathematicians and programmers both think critically in the abstract. Real world things are represented by objects and variables. The ability to translate from concrete to abstract also links the two fields.

There's a very good chance that if you're good at one, you will probably be good at the other.

Thank you

WTF?

Are you offering employment ?

Got it !
