Lizzy: Jane runs 3 kilometers in two hours. What is her speed in meters per minute?.
Me: Hmmm, let me think. I think this is the detailed solution:
Since 1 kilometer is equal to 1000 meters, then 3 kilometers is 3 x 1000 = 3000 meters. Since an hour has 60 minutes, then 2 hours is equal to 2 x 60 = 120 minutes. Therefore, her speed is 3000 meters / 120 hours = 25 meters per minute. Final answer: 25.
