Two shoots are tested under identical conditions.
The table shows the results.
Table
| Shoot | Leaf area in cm2\text{cm}^2cm2 | Water uptake in mm3\text{mm}^3mm3 | Time in minutes |
|---|---|---|---|
| P | 60 | 90 | 10 |
| Q | 40 | 80 | 10 |
Which statement correctly compares water uptake in mm3/min/cm2\text{mm}^3/\text{min}/\text{cm}^2mm3/min/cm2?
Q is greater: P is 1.50 and Q is 2.00.
P is greater: P is 0.20 and Q is 0.15.
P is greater: P is 2.00 and Q is 1.50.
Q is greater: P is 0.15 and Q is 0.20.
