Answer 1

Answer:

B) 480 kms

Step-by-step explanation:

Now, the distance covered by Chennai express in 2 hrs = 60 x 2 = 120 kms

Now, the distance covered by Chennai express in 2 hrs = 60 x 2 = 120 kmsLet the Charminar Express takes 't' hrs to catch Chennai express

Now, the distance covered by Chennai express in 2 hrs = 60 x 2 = 120 kmsLet the Charminar Express takes 't' hrs to catch Chennai express=> 80 x t = 60 x (2 + t)

Now, the distance covered by Chennai express in 2 hrs = 60 x 2 = 120 kmsLet the Charminar Express takes 't' hrs to catch Chennai express=> 80 x t = 60 x (2 + t)=> 80 t = 120 + 60t

Now, the distance covered by Chennai express in 2 hrs = 60 x 2 = 120 kmsLet the Charminar Express takes 't' hrs to catch Chennai express=> 80 x t = 60 x (2 + t)=> 80 t = 120 + 60t=> t = 6 hrs

Now, the distance covered by Chennai express in 2 hrs = 60 x 2 = 120 kmsLet the Charminar Express takes 't' hrs to catch Chennai express=> 80 x t = 60 x (2 + t)=> 80 t = 120 + 60t=> t = 6 hrs

Now, the distance covered by Chennai express in 2 hrs = 60 x 2 = 120 kmsLet the Charminar Express takes 't' hrs to catch Chennai express=> 80 x t = 60 x (2 + t)=> 80 t = 120 + 60t=> t = 6 hrs Therefore, the distance away from Hyderabad the two trains meet = 80 x 6 = 480 kms.

Answer 2

Answer:

Answer:   B) 480 kms

Explanation:

Now, the distance covered by Chennai express in 2 hrs = 60 x 2 = 120 kms

Let the Charminar Express takes 't' hrs to catch Chennai express

=> 80 x t = 60 x (2 + t)

=> 80 t = 120 + 60t

=> t = 6 hrs

 

Therefore, the distance away from Hyderabad the two trains meet = 80 x 6 = 480 kms.
