High speed trains in new york reach estimated speeds up to 4.96 x 10^1 meters per second. high speed trains in china estimated speeds of us to 0.96 x 10^2 meters per second.

1) explain if a high speed train in new york city travels fast or slower that a high speed train in china.

2) approximately how many times is the speed of the faster train with respect to the speed of the other?

High speed trains in new york reach estimated speeds up to 4.96 x 10^1 meters per second. High speed trains in china estimated speeds of us to 0.96 x 10^2 meters per second. 

1) explain if a high speed train in New York City travels fast or slower that a high speed train in china.   Compare 4.96*10^1 m/sec = 49.6 m/sec to
0.96*10^2 m/sec = 96 m/sec.  High speed trains in China travel nearly twice as fast as do high speed trains in NY.

2) Divide:  96 m/sec
                        The result is 1.94.
                  49.6 m/sec

H. S. trains in China travel approx. 1.94 times faster than do H. S. trains in NY.
