Answer:

B

Step-by-step explanation:

We'll use Natasha's location as 0 on a number line. To the left of her, 51/20 would be negative and 25/4 would be positive.

To find how far apart the dogs are, we would need to add the absolute value of each number:

|-51/20| + |25/4| however, this can also be rewritten as:

25/4 - (-51/20)
