Answer:
7,000 calories or 7 kilo cal/min.
Step-by-step explanation:
Lucia is using energy at a rate of 420 kilo calories per hour ice skating.
1 kilo calories = 1000 calories
420 kilo calories = 420,000 calories
1 hour = 60 minutes
∵ Lucia is using energy per 60 minutes = 420,000 calories
∴ She is using energy per minute =

Lucia is using energy 7,000 calories/minute.
Hi there,
I believe there are 3 questions.
Hope it helps :-)
The fraction of the vehicles that are not cars or motorcycles is 3/8.
Let's say that there are N vehicles on the road. 1/2 of these are cars and 1/8 are motorcycles.
So the number of vehicles that are not cars or motorcycles is given by:
N' = N - N/2 - N/8
Now we can take N as a common factor:
N' = N*(1 - 1/2 - 1/8) = N*(1 - 4/8 - 1/8) = N*(3/8)
Now we divide both sides by N to get:
N'/N = 3/8
So the fraction of the vehicles that are not cars or motorcycles is 3/8.
