Math Spies in London Introduction

Welcome back, Math Spy!  I hope you had a splendid vacation and are ready to get back to work.  I am still in London working on some intelligence for your next mission. 

In order to complete this mission, you need to know about time zones.  Local time for each of the cities in this mission is based on the time zone it is in.  As you travel east, you move ahead an hour for each time zone.  As you travel west, you subtract an hour for each time zone.  This is because as the earth rotates, each section or zone receives sunlight at a different time.

(If you have a globe and a flashlight, you may want to experiment with this.)

To help you with this mission, I have provided the chart below.  Copy and complete it to help you solve the problems:



Seattle, WA, USA

Pacific Daylight Time

(PDT)

Chicago, IL, USA

Central Daylight Time

(CDT)

New York, NY, USA

Eastern Daylight Time

(EDT)

London, England, UK

British Summer Time

(BST)

12:00 A. M.

2:00 A. M.

3:00 A. M.

8:00 A. M.

































After you have copied the chart click here to begin the mission.

Math Spies in London Question 1

In an undisclosed location near Seattle, Washington, Math Spies has a secret training ground.  The director wants you to call her at 4:15 P. M. BST.  What time do you need to call her PDT?

Math Spies in London Question 2

You are scheduled to meet a fellow operative when you land in Chicago.  Your laptop is still set to Seattle time and reads 2:25 P. M.  What time is it in Chicago?

Math Spies in London Question 3

You travel to New York, NY where you will take a trans-Atlantic flight to London.  You have a message to call the training ground in Seattle.   If it is 8:45 P. M. in New York, what time is it in Seattle?

Math Spies in London Question 4

You take a seven and a half hour flight from New York to London.  You arrive in London at 9:30 A. M. BST.  What time did you leave New York?
