Answer:
Luiz left home first, 10 minutes before arriving time.

We assume that both Luiz and Bianca left the homes and travelled at constant speed. The purpose of this problem is determining who left home first, which is related to time. From Kinematics, both can be represented by the following expression:
(Eq. 1)
Where:
- Travelled distance, measured in meters.
- Speed, measured in meters per second.
- Time, measured in seconds.
Then, times taken by each person is now calculated:
Luiz (,
)
Bianca (,
)
If both arrived at school at 8:55 AM, then Luiz left home at 8:45 AM. Luiz left home first, 10 minutes before arriving time.
