A train departs from a station and mas eastward with a constant velocity of 30 m/s. After traveling for 10 minutes, the train reaches a bridge 18km away. Simultaneously, a bird sitting on the bridge takes off and starts flying westward at a constant velocity of 15 m/s towards the train.
How long does it take for the train and the bird to meet?
Vrelative= 30+ 15 = 45 m/s
t= d/v = 400 secs (approximately 6 mins and 40 secs)
