Question

Answer 1

Answer:

The ratio of speed of both train, a:b is 5:4

Answer 2

Answer:

20 : 16

Step-by-step explanation:

Let the distance between Mumbai and Delhi be x

Train a takes 16 hours to reach Mumbai to Delhi

So, Distance = x

Time = 16

$Speed =\frac{Distance}{Speed}$

$Speed =\frac{x}{16}$

Train b takes 20 hrs

Distance = x

Time = 20

$Speed =\frac{Distance}{Speed}$

$Speed =\frac{x}{20}$

Ratio of their speeds = $\frac{x}{16}:\frac{x}{20}$

                                   = 20 : 16

Hence ratio of speed of both train is 20 : 16
