Final answer:
To calculate the MPG for a human consuming milk and compare it to the MPG of a car. Also, to determine the temperature difference in Celsius and Fahrenheit.
Step-by-step explanation:
To calculate the MPG (miles per gallon) for a human consuming whole milk, we first need to convert the calories per cup of milk into the calories burned while walking. Since walking burns 90 calories per mile, we divide the calories in a cup of milk (148 calories) by the calories burned per mile to get the MPG. To convert MPG to the MPG of a car, we need to know the MPG of the car and compare the two values.
For the second part of the question, a temperature decrease of 30°C is equal to a temperature decrease of 54°F.
