A) 500km.
B) 630km.
C) 660km.
D) 900km.
Correct Answer: D
Solution :
[d] Let the distance travelled by the second train be x km, the distance travelled by the first train is (x + 100) km. The time taken by each train is the same when they meet at the point T. \[\therefore \,\,\frac{x}{40}=\frac{x+100}{50}\Rightarrow x=400.\] \[P\frac{x+100\,\,\,\,\,\,\,T\,\,\,\,\,\,\,\,\,\,x}{{}}Q\] Thus distance travelled from P to Q = (400 +500) =900km.You need to login to perform this action.
