A train moves east with a speed of 31 m/s. A man on the train walks west
with a speed of 0.7 m/s relative to the train. How long does it take the man to
move 34 m relative to the train?
O A. 1.1 s
O B. 37 s
O C. 255
D. 49 s.
Since the man is walking 0.7m/s relative to the train, we can use that speed to determine how long it will take him to move 34m relative to the train. t = d/s, so 34/.7 ≈ 48.57s.
