Scientists counted cells in mitosis in two samples of cells grown in a laboratory. The whole cell cycle took a different length of time in each sample.
| Sample | Cells counted | Cells in mitosis | Time for one cell cycle |
|---|---|---|---|
| P | 120 | 18 | 20 hours |
| Q | 150 | 30 | 16 hours |
Determine which sample spends longer in mitosis, and calculate by how many minutes.
