Answer» Distance to be covered by the parrot=150m speed of train=10m/s speed of parrot=5m/s now consider the train with respect to parrot and not with respect to land. velocity of parrot=5 velocity of train=-10(∵the train is in opposite direction) so relative velocity of train w r t parrot = 5 - (-10)=15m/s now time = distance/speed = 150/15= 10s Like my answer if you find it useful! |
