Due to the technical snag in the signal system two trains start approaching each other on the same track from two different stations, 240 km away each other. When the train starts a bird also starts moving to and fro between the two trains at 60 kmph touching each train each time. The bird initially sitting on the top of the engine of one of the trains and it moves so till these trains collide. If these trains collide one and half hour after start, then how many kilometers bird travels till the time of collision of trains?
A. 90 km
B. 130 km
C. 120 km
D. 95 km
E. None of these
Answer: Option A
Solution(By Examveda Team)
Time taken to collide the trains, = one and half hour = $$\frac{3}{2}$$ h. So, in $$\frac{3}{2}$$ h bird travels, = $$\frac{{3 \times 60}}{2}$$ = 90 km.Join The Discussion
