A) \[150\,\,s\]
B) \[100\,\,s\]
C) \[50\,\,s\]
D) \[\frac{25}{3}s\]
Correct Answer: C
Solution :
Total distance travelled by two trains to cross each other \[=2000+300+200\] \[=2500\,\,m\] The total speed\[=20+30=50\,\,m/s\] \[\therefore \] Time,\[t=\frac{\text{total}\,\,\text{distance}\,\,\text{travelled}}{\text{total}\,\,\text{speed}}\] \[=\frac{2500}{50}=50\,\,s\]You need to login to perform this action.
