Two Trains From The Points A And B Moving In Opposite Direction, At T

1.	Two Trains From The Points A And B Moving In Opposite Direction, At The Point They Meet The Second Train Travels 120 Kms More Than The First. The Speeds Are 50kmph And 60kmph Respectively Find The Distance Between A And B?
Answer» We know that DISTANCE = TIME × speed Suppose FIRST TRAIN travelled the distance x kms from A. Then second train will travel the distance (x + 120) kms from B. Let they MET each other after t time ∴ (x + 120)/60 = (x/50) ⇒ x = 600 kms But the distances between two point is (x + x + 120) = 2x +120 = 2× 600 + 120 = 1320 km We know that Distance = time × speed Suppose first train travelled the distance x kms from A. Then second train will travel the distance (x + 120) kms from B. Let they met each other after t time ∴ (x + 120)/60 = (x/50) ⇒ x = 600 kms But the distances between two point is (x + x + 120) = 2x +120 = 2× 600 + 120 = 1320 km

Answer»

We know that

Suppose FIRST TRAIN travelled the distance x kms from A.

Then second train will travel the distance (x + 120) kms from B.

Let they MET each other after t time

∴ (x + 120)/60 = (x/50)

⇒ x = 600 kms

But the distances between two point is (x + x + 120)

= 2x +120

= 2× 600 + 120

= 1320 km
