Two airplanes are flying in the same direction in adjacent parallel corridors. at time t = 0, the first airplane is 10 km ahead of the second one. suppose the speed of the first plane (km/hr) is normally distributed with mean 550 and standard deviation 9 and the second plane's speed is also normally distributed with mean and standard deviation 535 and 9, respectively. a) what is the probability that after 2 hr of flying, the second plane has not caught up to the first plane? (round your answer to four decimal places.)b) determine the probability that the planes are separated by at most 10 km after 2 hr. (round your answer to four decimal places.)
