Billy was in Kyoto, where the temperature was 95°F.
Cathy was in London, where the temperature was 77°F.
Denny was in Washington, D.C., where the temperature was 91°F.
Evan was in Portland, where the temperature was 72°F.

explanation

Step 1
Find the temperature in degrees Fahrenheit in each city.

1. New York

F = 9/5C + 32

F = 9/5(30) + 32

F = 54 + 32

F = 86

2. London
30 °C – 5°C = 25°C

F = 9/5C + 32

F = 9/5(25) + 32

F = 45 + 32

F = 77

3. Washington, D.C.
New York's temperature (°F) + 5

86°F + 5°F = 91°F

4. Portland
London's temperature in °F - 5°

77°F - 5°F = 72°F

5. Kyoto
London's temperature in °C + 10°

25°C + 10°C = 35°C

F = 9/5C + 32

F = 9/5(35) + 32

F = 63 + 32

F = 95

Step 2
Place the cities in order from highest temperature to lowest temperature.

Kyoto
Washington, D.C.
New York
London
Portland

Step 3
Make a chart and use the clues to find out where each person was traveling.
