Question 8

The scientists also measured the mean rate of flow of blood plasma into the kidneys. The results obtained were: for Group A (Drug X), the mean plasma flow rate was 385 cm3 min-1; for Group B (Drug Y), it was 340 cm3 min-1; and for Group C (placebo), it was 297 cm3 min-1. The mean rate of flow of blood plasma is 55% of the mean rate of flow of blood into the kidneys. How much greater is the flow of blood into the kidneys with Drug X (Group A) than with the placebo (Group C) over the 3 hours of the investigation? Give your answer in cm3\text{cm}^3cm3.
