A student carries out an investigation into how quickly oil flows through a funnel. The diagrams show the setup and the amount of oil in the measuring cylinder at the beginning of the experiment, and again after one minute. What is the rate at which oil flows through the funnel during that one minute?
- A$0.73\,\text{cm}^3\,\text{s}^{-1}$
- B$0.80\,\text{cm}^3\,\text{s}^{-1}$
- C$44\,\text{cm}^3\,\text{s}^{-1}$
- D$48\,\text{cm}^3\,\text{s}^{-1}$
