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

Answer:
Because soil analysis can indicate the existence of flammable substances. Which indicates that the fire was caused by someone in a criminal manner.
Explanation:
As we know, the soil represents the surface layer of the earth where the plants are fixed and remove the nutrients they need to survive.
The soil is formed through the weathering of the rocks having the minerals that its original rock has. The soil has no flammable substance, as it is basically made up of sand, clay and silt. In addition, the soil is a porous environment, which allows any liquid released onto it to infiltrate at a considerable speed.
For this reason in the investigation of a criminal fire, the analysis of soil samples can be very useful. This is because soil analysis can indicate the presence of some flammable substance that has infiltrated. This can confirm that the fire was provoked and was criminal.
