Q:

A train travels 360 km at a uniform speed. If the speed had been 5 km/h more, it would have taken 1 hour less for the same journey. Find the speed of the train?

A) 42 kmph	B) 43 kmph
C) 40 kmph	D) 45 kmph

Answer & Explanation Answer: C) 40 kmph

Explanation:

We know that, Speed = Distance/time

Let the speed of the train be = x kmph

           NORMAL SPEED                           SPEED 5 KMPH MORE

          Distance = 360 Km                         Distance =360

          speed    = X Kmph                        Speed = (x+5)

            Time =360/X                              Time =360/(x+15)

For the same journey if the speed increased 10 kmph more it will take 1 hour less

Time with original speed - time with increased speed = 1

=> (360/x) - (360/x+10) = 1

=> (360(x+5)-360x)/x(x+5) =1

=> 360X + 1800 -360X = X(X+5)

  => X^2 + 5x - 1800 = 0

X = 40 or -45

X cannot be negetive value

X = 40 kmph.
