Final answer:
The average rate of liquid nitrogen consumption on a 3-hour trip is 66.7 L/hour, but this answer does not match the given options (a) 22.7 L/h, (b) 33.3 L/h, (c) 44.4 L/h, or (d) 55.5 L/h, indicating a possible error in the question.
Step-by-step explanation:
The question is asking us to calculate the average rate of liquid nitrogen consumption for dairy trucks on a delivery trip that lasts 3.00 hours, given that 200 liters (L) are required for the entire trip. To find the average rate of consumption, we divide the total volume of liquid nitrogen used by the duration of the trip.
We have 200 L of liquid nitrogen for a trip lasting 3 hours.
The formula for the average rate of consumption (R) is:
R = Total Volume of Liquid Nitrogen / Duration of the Trip
Plugging the values into this formula gives us:
R = 200 L / 3 hours
So, the average rate of consumption is:
R = 66.7 L/hour
However, there might be an error in the question, because based on the calculation, none of the options provided (a, b, c, d) matches the correct answer of 66.7 L/hour. Hence, the given answer options may need verification as the average rate of consumption does not fit any of them.
