Bird is flying 120 km/hr between B to R. Two trains at B to R at 60 kmph. The distance traveled by the bird before it is killed? Choose the correct choice:
A) 90 kms .	B) 100 kms .	C) 110 kms .	D) 120 kms .	E) 130 kms .

Rationale: it will depend on the distance between b and r . if distance between b and r is 120 kms , time taken by trains before collision = 120 / ( 60 + 60 ) = 1 hr distance traveled by bird in 1 hr = 120 kms . so the distance traveled by the bird before it is killed = 120 kms . answer : d
Answer: D
