Answer 1

For Dolly her average velocity is 170/45 = 3.8 m/s. Straight forward right?

Answer 2

Good. Finish the rest.

Answer 3

Oh wait! wait!! I'm wrong. The formula is total distance traveled/total time taken. Those distances are the distance AWAY from the barn, NOT the distance traveled by the sheep. We need the distances traveled by the sheep.

Answer 4

We want the distances COVERED by the sheep, not the distance away from the barn.

Answer 5

Yes. The problem will be resolved. Since Dolly is 170 meters AWAY from the barn, and the distance between the pasture and the barn is 200 m. Dolly has only covered 80 meters in 45 seconds (200-140). The average velocity for Dolly is 80/45= 1.8 m/s.

Answer 6

Subtract the distances from 200 and divide by 45!. Like I showed above.

Answer 7

Lol. I think you should know if you are right.

Answer 8

I made another mistake. The distance from the pasture to the barn is 250 m. I thought it said 200, please subtract from 250 not 200. Sorry.

Answer 9

Distance covered by Dolly is 250-170 = 80 m. Average velocity is 80/45 = 1.7m/s
Distance covered by Fluffy is 250-115=135. average velocity is 135/35 = 3m/s

Answer 10

D is the answer. The question said from slowest to fastest.
