2 QUESTION HELP 69 POINTS 1) The Shinkansen (bullet train in Japan) makes a trip from Tokyo Station to Kyoto station in 2.0 hours and 14 min. The distance traveled is 460 km (to two significant figures). Determine the average velocity of the train in meters per second (m/s). [conversions: 1 km = 1000 m, 1 hr = 3600 s, 1 min = 60 s] *Round your answer to two significant figures* *
