Sai Bhargav  (5 years ago)

Let 'x' be the Original Speed
Given Speed =8/11(Original Speed)
As Speed Is Inversely Proportional to Time
11/8(x)=55/2
x=55/2*8/11
x(original Speed)=20 hrs.
If he runs with Original Speed then Saved Time= 55/2 -20
= 7.5hrs

Let the speed of the train be x.
Then 8x/11 + x = 27.5 => x = 16 hours.
Therefore it could save 11 hours 30 minutes of the train had run at its original speed .
