A) 5 units
B) 7.5 units
C) 10 units
D) 12.5 units

Answer 1

To find the distance Sarah walks, set up an equation representing the total distance walked by both girls and solve for x. The correct answer is 10 units.

Step-by-step explanation:

To find the distance Sarah walks, we can assign a variable to the distance Sarah walks, let's call it x. Since Sarah walks twice as far as Susy, we can say that Susy walks x/2 units. The total distance they walked is 15 units, so we can set up the equation x + x/2 = 15. To solve for x, we can multiply the equation by 2 to get 2x + x = 30. Combining like terms, we have 3x = 30. Dividing both sides by 3, we find that x = 10.

Therefore, Sarah walks 10 units, which means the correct answer is C) 10 units.
