The position of a particle as a function of time t
A passenger train of length 60 m travels at a speed of 80 km/hr. Another freight train of length 120 m travels at a speed of 30 km/hr. The ratio of times taken by the passenger train to completely cross the freight train when: (1)they are moving in the same direction, and (ii) in the opposite directions is
