A) 1 pm
B) 12 noon
C) 12:30 pm
D) 1:30 pm
Correct Answer: B
Solution :
[b] Let both trains meet x h. Train B starts, after \[\therefore \]Distance covered by first train\[=(x+2)\times 70\,km\]and distance covered by second train \[=x\times 110\,km\] \[\therefore \] \[110x+140+70x=500\] \[\Rightarrow \] \[180x=360\] \[\Rightarrow \] \[x=2\] Hence, both trains meet each other at 12 noon. |
