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 :
Hence, Lucia is using 7000 calories per minute.

Answer:
C
Step-by-step explanation:
The answer is going to be miles per quart. So B is wrong.
12 gallons allows you to travel 192 miles
1 gallon permits 192 / 12 = 16 miles / gallon. (Must be a truck of some kind).
1 gallon permits 16 miles of driving.
4 quarts (in 1 gallon) permits 16 miles of driving.
1 quart gives 16/4 = 4 miles / quart.
The answer is C.
==========================
There is a slightly shorter way
12 gallons contains 12 * 4 quarts = 48 quarts.
48 quarts permit 192 miles
1 quart permits 192/48 = 4 miles
4miles / quart.
The answer is still C
Yes because 13-5=8. not any other single number can be identified in the missing number
