Four sheep are traveling the 250 m distance from the pasture back to the barn. After 45 seconds, their distances from the barn are as follows: Dolly - 170 m, Fluffy - 115 m, Ellie - 90 m, Ma - 200 m. According to average velocity, how would the sheep rank from slowest to fastest?

Traveled               Average velocity
Dolly    (250 - 170 = 80)          80*(4/3) = 320/3 mile/hr
Fluffy   (250 - 115 = 135)        135*(4/3) = 540/3
Ellie     (250 - 90 = 160)          160*(4/3) = 640/3
Ma       (250 - 200 = 50)          50*(4/3) = 200/3
Slowest to fastest: Ma - Dolly - Fluffy - Ellie
