Explanation:

Step1: Identify time - zone differences

The continental United States has four main time - zones: Eastern, Central, Mountain, and Pacific. Eastern is 3 hours ahead of Pacific, Central is 2 hours ahead of Pacific and 1 hour behind Eastern, and Mountain is 1 hour ahead of Pacific and 2 hours behind Eastern.

Step2: Answer question 8

You leave Boston (Eastern time - zone) at 8:00 A.M. The flight takes 6 hours. So in Boston, when you land, it will be 8:00 A.M.+6 hours = 2:00 P.M.

Step3: Calculate San Francisco time when landing

San Francisco is in the Pacific time - zone, 3 hours behind Eastern. When it is 2:00 P.M. in Boston, in San Francisco it will be 2:00 P.M. - 3 hours=11:00 A.M.

Step4: Answer question 9

San Francisco is in the Pacific time - zone and Chicago is in the Central time - zone. Central is 2 hours ahead of Pacific. If you leave San Francisco at 5:30 P.M. (Pacific time), in Chicago it is 5:30 P.M.+2 hours = 7:30 P.M.

Step5: Answer question 10

You leave San Francisco at 5:30 P.M. (Pacific time). The flight takes 4 hours, so you arrive in San Francisco at 5:30 P.M.+4 hours = 9:30 P.M. (Pacific time). In Chicago (Central time - zone, 2 hours ahead of Pacific), it will be 9:30 P.M.+2 hours = 11:30 P.M.

Answer:

1. In Boston: 2:00 P.M.; In San Francisco: 11:00 A.M. because San Francisco is 3 hours behind Boston.
2. 7:30 P.M.
3. 11:30 P.M. because Chicago (Central time - zone) is 2 hours ahead of San Francisco (Pacific time - zone) and the flight duration is 4 hours from a 5:30 P.M. (Pacific time) departure.
