Q:
A) 19 kmph | B) 13 kmph |
C) 7 kmph | D) 9 kmph |
Answer: A) 19 kmph
Explanation:
Explanation:
Let the speed of the slower train = p kmph
ATQ,
Speed of the faster train = (p + 6) kmph
Then,
(p + p + 6) x 5 = 160
10p + 30 = 160
10p = 130
p = 13 kmph
Then, speed of the faster train = p + 6 = 13 + 6 = 19 kmph.
