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 6 4
Buster 2

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 AU’s. On a number line, place each planet according to it’s distance from the sun (to scale). Let the sun’s 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 moon’s 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.
