Kelvin is at his house located at $$( 3,4 )$$ on a coordinate plane and walks to the store located at $$( 1,0 )$$ . The store is located exactly half way between Kelvin's house and Mitch's house. To the nearest tenth, what is the distance between Kelvin's house and Mitch's house? A. $$4.2$$ B. $$4.5$$ C. $$5.7$$ D. $$8.9$$

1=$$\frac{3+ x}{2}$$

x=-1

0=$$\frac{4+ y}{2}$$

y=-4

(-1,-4) mitch house

distance = $$\sqrt{(- 1- 3)^{2}+ (- 4- 4)^{2} }= \sqrt{16+ 64}= \sqrt{80}= 8.9$$
