A) 190 kmph
B) 160 kmph
C) 180 kmph
D) 130 kmph
Correct Answer: C
Solution :
Let speed of the car be \[x\] kmph. Then, speed of the tram \[=\frac{200}{100}x\] \[=2x\] \[\therefore \] \[\frac{150}{x}-\frac{150}{2x}=\frac{25}{60}\] \[\Rightarrow \] \[\frac{150}{x}-\frac{150}{2x}=\frac{5}{12}\] \[\frac{150}{2x}=\frac{5}{12}\] \[\Rightarrow \] \[x=\frac{12\bullet 150}{100}=180\] kmph.You need to login to perform this action.
