I gave my students this multiple choice question: A group of Canada geese left a Florida lake in the spring. The geese arrived at a Maine lake 2,000 km away in 40 days. If the geese traveled at a constant rate, how far did the geese travel on the first day?

Only one answer is correct among these 4 choices:
- 5 km
- 20 km
- 40 km
- 50 km

Could you tell me which one is correct?

50 km
