Suppose you wanted to reach Alpha Centauri in 200 years.

A.How fast would you have to go, in {km/hr}?

B. How many times faster is the speed you found in part A than the speeds of our fastest current spacecraft (around 50000 {km/hr})?

Alpha Centuri is 4.4 ly away (1 ly is 9.46x10 to the 12th power) so i think that it would be 4.1624x 10 to the 14th power km away
 
First, convert 200 years to hours.

Second, convert light years to kilometers. Your conversion from light years to meters seems to be off, though I am not sure of the units of 9.46 x 10^12 since you did not specifically state the units.
