Question

Starting from the same place, Anaad walks due west and Cala walks due east. On the number line, 0 represents their starting point; negative values represent the distance in feet, traveled west; and positive values represent the distance in feet, traveled east. The figure shows a number line. There are 10 tick marks to the left of 0 and 10 tick marks to the right of 0. The tenth tick mark to the left of 0 is labeled negative 700, and the tenth tick mark to the right of 0 is labeled 700. The seventh tick mark to the left of 0 is labeled Anaad, and the eighth tick mark to the right of 0 is labeled Cala. How many feet apart are Anaad and Cala on the number line?

Answer 1

-700 and +700

Explanation:

Starting from the same place, Anaad walks due west and Cala walks due east. On the number line, 0 represents their starting point; negative values represent the distance in feet, traveled west; and positive values represent the distance in feet, traveled east. The figure shows a number line. There are 10 tick marks to the left of 0 and 10 tick marks to the right of 0. The tenth tick mark to the left of 0 is labeled negative 700, and the tenth tick mark to the right of 0 is labeled 700. The seventh tick mark to the left of 0 is labeled Anaad, and the eighth tick mark to the right of 0 is labeled Cala. How many feet apart are Anaad and Cala on the number line?

Answer 2

1050 ft

Explanation:

Each tick mark apparently represents a distance of 700/10 = 70 ft. Then the 7+8 = 15 tick marks separating Anaad and Cala represent ...

... 15 × 70 ft = 1050 ft
