0.1 km 1.5 km 10 km 90 km
I gave my students this multiple choice question: Jeremy walked at an average rate of speed of 3 kilometers per hour (km/h). How far had Jeremy walked in 30 minutes?

Only one answer is correct among these 4 choices:
- 0.1 km
- 1.5 km
- 10 km
- 90 km

Could you tell me which one is correct?

1.5 km
