Lúcia is using energy at a rate of 420 kilocalories (kcal) per hour (h) ice skating.

kakasveta [241]

Answer:

7000 cal/min

Step-by-step explanation:

It is mentioned that, Lucia is using energy at a rate of 420 kilo calories per hour ice skating

We know that,

1 kilo calories = 1000 calories

Using unitary method :

420 kilo calories = 420,000 calories

Also,

1 hour = 60 minutes

In this case, Lucia is using energy per 60 minutes = 420,000 calories. So,energy used by her per minute is :

$E=\frac{420000}{60} =7000 calories$

Hence, Lucia is using 7000 calories per minute.
