Final answer:
The minimum clearance between the bottom of the fire extinguisher and the floor should be 0.89 m.
Step-by-step explanation:
The question is asking for the minimum clearance between the bottom of a fire extinguisher and the floor. To determine this, we need to look at the given heights. Let's consider the height of a person who is 1.715 m tall. The bottom of the extinguisher is 0.825 m from the floor. Therefore, the clearance between the bottom of the extinguisher and the floor is 1.715 - 0.825 = 0.89 m. So, the minimum clearance between the bottom of the extinguisher and the floor should be 0.89 m.
