I think you should complete your answer it is half............

Answer 2

Answer:

Total distance between a and b is 60 km

Step-by-step explanation:

Step 1:

Train x = 60 km/h  

Train y = 30 km /h

Step 2:

Train x begins first at 60 km/h.  

1/2 × 60 = 30 km

Step 3:

Let the total distance be D.  

The distance remaining is (D - 30) km

Let the relative distance = 30 km

Step 4:

Relative speed = 60 + 30 = 90 km/h

Time taken for them to meet is:

30/90 = 1/3 hrs  

They meet after 1/3 hrs.  

Step 5:

The total distance between a and b is:

(60 × 1/3 + 30)  + (30 × 1/3)

(20 + 30) + 10 = 60 km
