PROBLEMS ABOUT LOCAL AND STANDARD TIME 137

The lines marking the boundaries of time belts are not meridians. They are irregular north and south lines connecting stations (usually division points) on important railroads.

Problems about Standard and Solar (Local) Time

Use the map and your knowledge of longitude and time to help you solve these problems.

1. In which time belt do you live? Is your local time faster or slower than your standard time?

2. What is the difference between Central time and the local time of places on the 90th meridian?

3. Frank said, "My local time is 20 min. faster than Central time." What was his longitude?

4. James said, "Central time is 20 min. slower than my local time." What was his longitude?

5. If the boys mentioned in problems 3 and 4 live in places 100 miles apart, what must be the direction of each from the other?

6. Mary said, "My local time is the same as Eastern time." Where does she live?

7. When it is 9 A.M. standard time at Denver, what is the standard time at New York City?

8. When it is 1 P.M. standard time at Boston, what is the standard time at Portland, Ore.?

9. If you know your longitude in degrees and minutes, how can you compute the difference between your local and your standard time?

10. Does Chicago have noon (sun time) before or after Memphis, Tenn.? Why?

The problems in this exercise are based on the railroad map and time tables shown on pages 138 and 139.

1. How many hours and minutes is the run according to the table from Chicago to Denver? From St. Louis to Denver? From Denver to Salt Lake? From Salt Lake to Los Angeles? From Ogden to San Francisco?

2. What is the distance from Chicago to Los Angeles? From St. Louis to Los Angeles? From Chicago to San Francisco?

3. John leaves Chicago Monday at 11 P.M. When will he arrive at Salt Lake City? When will he arrive at Los Angeles?

4. What change in time is made at McCook? At Salt Lake City? At Ogden? Does the table show the actual number of hours traveled between Chicago and Los Angeles?

5. A person leaving St. Louis at 9:01 P.M. for San Francisco wishes to go by the quickest route. Which is it, the Western Pacific out of Salt Lake City or the Southern Pacific out of Ogden? How many hours will be saved by selecting the right route?

6. How often and in which cities is the time changed in traveling from Chicago to San Francisco? From Chicago to Los Angeles?

7. Excursion tickets from St. Louis to Denver and return have been sold at $25 each. At this price what was the fare per mile?

8. If a tourist leaves Chicago at 11 P.M. on Saturday, when should he arrive at San Francisco if there is no delay?

9. If you should leave Chicago on Saturday for Los Angeles and should spend a day at Denver, one at Colorado Springs, and should leave Salt Lake City on No. 7 (see the time tables), when would you arrive at Los Angeles? Why should one want to stop at these points?

10. Estimating the railroad fare at 3¢ per mi. and the Pullman fare at $23 for a lower berth, find the cost of a full fare railroad and Pullman ticket from Los Angeles to Chicago if there is an 8% war tax on railroad and Pullman transportation.

11. The Pullman fare for an upper berth is 80% of that of a lower. What would have been the total fare from Chicago to Los Angeles if you had paid for an upper? How

much can a person save between Chicago and Los Angeles by buying an upper instead of a lower berth?

12. Make other problems based on pages 138 and 139, and after solving them yourself give them to a classmate for solution.

13. A man paid $5.54 for a railroad ticket between two towns. The war tax was 8%. What was the fare itself? At 3 cents a mile, what was the distance?

14. I paid $20.28 for railroad and Pullman tickets between two cities. The regular Pullman ticket I knew was $3.00 and the railroad fare was 3 cents per mile. The war tax was 8% on railroad fares and 8% on Pullman tickets. What was the railroad fare and the distance?

15. In Jan. 1921, I paid $15.29 for railroad and Pullman tickets from Chicago to St. Louis. The regular Pullman ticket I knew was $3.75, and the railroad rate was 3.6¢ per mile. The war tax was 8% each on Pullman and on railroad tickets. What was the railroad fare and the distance?

16. Plan the route and determine the probable cost of a round trip to your state capital from your nearest railway station. Plan to spend one day at the capital. Why should young people want to visit their state capital?

17. Plan the route, the traveling time, and the probable cost of a round trip from your town to Washington, D.C. Mention some points of interest bearing on your school studies, which might make such a trip valuable to boys and girls.

18. In January, 1919, Eric Springer flew a plane from Dayton, Ohio, to Cleveland, Ohio, distance 215 miles, in 75
