Question

The distance between two stations is 425 kilometre. Two trains start simultaneously from these stations on parallel tracks to cross each other. The speed of one of them is greater than that of the Other by 5 kilometre per hour. If the distance between the two trains after 3 hour of their start is 20 kilometre, find the speed of each train?

Answer 1

Step-by-step explanation:

answer answer of that question is 20/ 3 = 6.66

5/1 = 5

Answer 2

Given:

Distance between two stations=425 km

Speed by which one train  is greater than other=5 km/hr

Distance between two trains after 3 hour of their start=20 km

To Find:

Speed of each train

Solution:

• Let,the speed of one train be x km/h
• Then,the speed of other train=(x+5) km/h
• The distance travelled by the 1st train in 3 hours=(3x) km
• The distance travelled by the second train in 3 hours=3(x+5) km

    ∴  $425-[3x+3(x+5)]=20$

    ⇒ $425-3x-3x-15=20$

    ⇒ $6x=390$

    ⇒ $x=65$

So,the speed of the first train =65km/h

Speed of the second train=(65+5)km/h
