0.75 m/h 20 m/s 80 m/h 1,200 m/h
I gave my students this multiple choice question: Students observed a turtle in the schoolyard. They measured the distance that the turtle traveled in 30 minutes. If the turtle walked 40 meters in that time, what was its average speed?

Only one answer is correct among these 4 choices:
- 0.75 m/h
- 20 m/s
- 80 m/h
- 1,200 m/h

Could you tell me which one is correct?

80 m/h
