A) 990 km
B) 1200 km
C) 1320 km
D) 1440 km
Correct Answer: C
Solution :
Let train A start from station A and B from station B. Let the trains A and B meet after t h. \[\therefore \] Distance covered by train A in \[t\,\,h=50\,t\] Distance covered by train B in \[t\text{ }h=60\,t\,\,km\] According to the question, \[60\,t-50\,t=120\] \[\Rightarrow \] \[t=\frac{120}{10}=12\,\,h\] \[\therefore \] Distance\[AB=50\times 12+60\times 12\] \[=600+720\] \[\Rightarrow \] \[=1320\text{ }km\]You need to login to perform this action.
