A.)Here, High speed Train in New York = 4.96 * 10¹ = 49.6 m/s
High speed Train in China = 0.96 * 10² = 96 m/s
As 96 > 49.6
Train in China is faster than in New York!!
B.) You need to divide, New York Train's speed from China's, as follows:
China / New York = 96 / 49.6 = 1.93
So, your final answer for this part is 1.93 times
Hope it helped!
