Question

The Japanese JR-Maglev is the fastest non-conventional train in the world, having achieved 581 km/hr on a magnetic-levitation track. a) Convert 75% of this speed to mi/hr. b) With the speed determined in part a) what distance in miles can be traveled if the JRMaglev left a station at 1:10 pm one afternoon, arriving at its destination at 2:47 pm? c) Compare this distance to the distance travelled if the JR-Maglev ran at a full speed. 1. Make a meaningful sketch of this problem. 2. Identify and label the known quantities. 3. What is the question being asked? 4. Which of the five principle motion equations would be most helpful at solving this equation? 5. Solve this problem and draw a conclusion on the answer (e.g. does it make sense)

Explanation / Answer

a) 581 km/hr = 361 mi / hr
75 p.c = 270.75 mi/hr
b) Distance = 270.75*97/60 = 437.7125 mi
c) This distance is 75 pc of the full max distance
