Final answer:
Typical flow rate units are cubic meters per second (m³/s) or liters per minute (L/min). The correct answer to the question is a. cubic meters per minute.
Step-by-step explanation:
The commonly used units for flow rate are related to the volume of fluid that passes a certain point within a given time frame. The standard SI unit for flow rate is cubic meters per second (m³/s), but other units can be used, such as liters per minute (L/min), which is also a popular unit of measurement. This is because one liter equates to 1/1000 of a cubic meter (10-3 m³) or 1000 cubic centimeters (10³ cm³). In the context of the problem provided, the options given refer to different measures, but only one pertains to the flow rate of fluid.
To directly answer the student question, the typical flow rate units are a. cubic meters per minute. The other options, such as miles per hour (b) and feet per second (c), are units of speed rather than flow rate.
