Many methods to solve this but the most algebraic one is:
D= S * t

Let s be average speed and t be the initial time without any increase in speed.
So,
450 = S * T

Then,from the given information,

450 = (S+5) * (T-1)
Solve for S from both equations we have S = 45.

Hope this helps....
You can see options and solve directly also by trying the options.For this always start with option E and backwards.

Thanks,

Is there any other method other than Algebra?

As i said try out the options directly and if you are lucky you can get the answer in 20 seconds!!!
