Distance travelled by the train = 480 km Let the speed of the train be x kmph Time taken for the journey = 480/x Given speed is decreased by 8 kmph Hence the new speed of train = (x – 8) kmphTime taken for the journey = 480/(x – 8)� 1280 = x2�– 8x �x2�– 8x – 1280 = 0 On solving we get x = 40 Thus the speed of train is 40 kmph

dayanidhi0429: okay...frnds
