A car moving at 75 km/h meets a train of length 2.9 km moving at 35 km/h along a track parallel to the road. What distance does the car travel in passing the length of the train given that they travel
a) in the same direction;
75-35=40 km/hr=speed at which car is passing the length of the train
travel time to pass length of train=2.9/40=0.0745 hr
distance car traveled=75*0.0725=5.44 km
..
b) in different directions
75+35=110 km/hr=speed at which car is passing the length of the train
travel time to pass length of train=2.9/110=0.0264 hr
distance car traveled=75*0.0264=1.98 km
