A) 100
B) 115
C) 125
D) 150
Correct Answer: C
Solution :
[c] Let the length of both the trains be x m. Then, relative speed of the trains \[=90-60=30\,km/h\] \[=30\times \frac{5}{18}=\frac{25}{3}\,m/s\] Now, using speed\[\text{Speed=}\frac{\text{Distance}}{\text{Time}}\] \[\text{=}\frac{25}{3}=\frac{2x}{3}\] \[\therefore \] \[x=125\,m\] |
