Final answer:
To find the total amount administered per hour, we must add the initial quantity spread over 8 hours (500/8, which equals 62.5 mL) to the continuous rate, resulting in 125 mL per hour. This is the rounded total amount administered per hour.
Step-by-step explanation:
The student's question involves calculating the total amount of liquid administered over a period of 8 hours, and the rate at which the liquid is administered. The question implies two parts: the initial quantity of 500 mL provided over 8 hours, and a continuous rate of 62.5 mL per hour. To solve this, the student needs to understand both basic division and the concept of rates.
Using the given information, the total amount in milliliters (mL) administered per hour would be the sum of 500 mL divided by 8 hours plus the consistent rate of 62.5 mL per hour. The mathematical expression for this calculation is (500 / 8) + 62.5. After performing the division 500 / 8, we get 62.5. Therefore, 62.5 + 62.5 equals 125 mL per hour. When this value is rounded as instructed (potentially to the nearest whole number), the final answer would be 125 mL/hr.
