In Galileo's attempt to determine the speed of light, he and his assistant were located on hilltops

Question:

In Galileo's attempt to determine the speed of light, he and his assistant were located on hilltops about 3 km apart. Galileo flashed a light and received a return flash from his assistant.

(a) If his assistant had an instant reaction, what time difference would Galileo need to be able to measure for this method to be successful?

(b) How does this time compare with human reaction time, which is about 0.2 s?
