Question

two trains go with a speed of 50 km hour and 65 km per hour start at the same time from two station 3:45 km apart if both the twins train opposite direction after how many hours will they cross each other​

Answer 1

Answer:

Step-by-step explanation:

Speed of train1= 50km/hr

Speed of train2= 65km/hr

For the trains to cross each other, the sum of the distance travelled by both trains should be equal to the distance between the train stations i.e. 345km.

Let the time taken by the trains to cross each other be= x

Distance travelled in x hrs by:

Train1= 50x

Train2= 65x

Equation:

50x+65x= 345

115x= 345

x= 345/115

x=3hrs

Therefore time taken by the two trains to cross each other= 3hrs
