A train moving 561 m per minute in a south-to-north direction passed near Austin's house. Because the train was 50 m long and was only 10 km from Austin's
house, it was easy to both hear and see the train
Question:
Which statement describes the train's motion?
o Its speed was 9.35 m/s
Its velocity was 561 ms
