I need help on this I can give 10 points.

Answer:
[tex]5\frac{3}{4}[/tex]
Step-by-step explanation:
bottom is below, so we use a negative number
[tex]bottom = -3\frac{1}{2}\\top = 2\frac{1}{4}\\distance = top - bottom = 2\frac{1}{4} - (-3\frac{1}{2}) = 2\frac{1}{4} + 3\frac{1}{2} = 5\frac{3}{4}[/tex]
