D) Matthew travels two and one-half miles to get to
Fudgin [204]

Answer:

5/6 miles

Step-by-step explanation:

Matthews travels 2.5 miles → this is 3 times the distance that Jennifer travels

Jennifer travels 2.5 / 3 miles  = 5/6 miles

because,

2.5 =  2 and 1/2 = 5/2

(5/2) ÷ 3 = (5/2) *(1/3) = 5*1/ 2*3 = 5/6
