Question

A high-speed train in Japan travels a distance of
300. kilometers in 3.60 × 10^3 seconds. What is
the average speed of this train?
(1) 1.20 × 10^–2 m/s (3) 12.0 m/s
(2) 8.33 × 10^–2 m/s (4) 83.3 m/s

1 Answer

  • Distance traveled = 300 km
    Time of travel = 3.6 x 10³ s

    Average speed = distance/time
      = (300 x 10³ m)/(3.6 x 10³ s)
      = 83.3 m/s

    Answer:  (4)  83.3 m/s
