• 1. Marathon The map on the right is being used
  to plan a 26.3 mile marathon. Coordinates are
  given in miles. The locations of the
  participating towns on the map are Angel City
  (0, 0) Buster (4, 3) Clearfield (9, -2) and
  Curtis (-1, -4).
• Which of the planned routes is nearest to the
  26.3 mile requirement?
• Curtis to Clearfield to Angel City to Curtis
• Curtis to Clearfield to Buster to Angel City to
  Curtis
• Curtis to Buster to Clearfield to Curtis
• Curtis to Buster to Angel City to Clearfield to
  Curtis

• 2. Mapping the Solar System Astronomical Units
• Astronomers use different units of measure to
  calculate the distances that the planets are from
  one another and from the sun. They can use
  miles, kilometers, light years. Another unit is
  an astronomical unit (AU). One AU is equal to
  the distance from the earth to the sun, or
  92,960,000 miles.
• In the table the distances of the planets from
  the sun are listed in AUs. On a number line,
  place each planet according to its distance from
  the sun (to scale). Let the suns position be at
  point zero.
• Which planets are between Earth and the sun?
• Which planet is closest to the Earth?
• Recently NASA sent a probe to Mars. How far is
  Mars from Earth?
• Which two neighboring planets are furthest apart?
• The distance between Earth and the moon is
  240,000 miles. Calculate the moons distance
  from the Earth in astronomical units.
• Because the moon rotates around the Earth, it is
  sometimes between Earth and the sun (solar
  eclipse) and other times the Earth is between the
  moon and the sun (lunar eclipse). Use exercise
  f to position the moon on the number line with
  respect to the Earth and the sun during a solar
  eclipse and during a lunar eclipse.
