Question

Train ‘X’ take 2 hours more than train ‘Y’ to cover certain distance ‘D’ while train ‘X’ can cover (D +
160) is 8 hours. If speed of train ‘Y’ is 50% more than that of train ‘X’, then find the speed of train ‘Y’?

Answer 1

Answer:

Let speed of train 'X' = x km/hr

And, speed of train 'Y = 1.5x km/hı

According to the question

2 = D/x - D/1.5x ........(i)

And, D+160/8 = x .....(ii)

On solving (i) & (ii)

X= 80 kmph

Speed of train Y = 120 kmph
