Step-by-step explanation:

In order to solve this problem, we just need to transform from kilocalories per hour to kilocalories per minutes.

We know that, Lucia is using energy at a rate of 420 kcal/hr. So, if 1 hour equals 60 minutes, we just need to use this to find the answer

Therefore, Lucia is using energy at a rate of 7 kilocalories per minute.
