Question
The ratio of the speeds of Train A, Train B, and Train C
is 3:5:7 respectively. Train D moves 6 km/hr slower than Train B. If the difference between Train C and Train A’s speed is 48 km/hr, what is the ratio of speed of Train B to Train D?Solution
Let speeds be 3x, 5x, and 7x respectively.
So, Train D’s speed = 5x - 6
ATQ,
7x - 3x = 48
Or, 4x = 48
Or, x = 12
Train B = 5 × 12 = 60
Train D = 60 - 6 = 54
Required ratio = 60:54 = 10:9
