Can someone please answer this question please answer it correctly and please show work please help me I need it

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)
