Cally, Deena and Juan are working on a GCSE project.
They are each in a different class. Cally, Deena and Juan each record the journey times to school of pupils in their own class.
The times for pupils in Cally’s class are shown in the table below.
| Journey time, t (minutes) | Number of pupils |
| 0 | 5 |
| 5 | 5 |
| 15 | 6 |
| 30 | 5 |
| 50 | 4 |
