Question
In how much time will a train running at a speed of 48
km/hr cross the other train running in opposite direction? Statement I: The length of the two trains is 90 metres and 120 metres respectively. Statement II: The speed of the second train is 60 km/hr.Solution
From I, Distance = 120 + 90 = 210 m. From II, Relative speed = 48 + 60 = 108 km/hr. ∴ Time = (210 ×18)/(108 × 5) = 7 sec. Therefore, both the statement I and II together are required to answer the question.
