This is impossible to answer. This all depends on what you define as a 'person.' If you are talking about the first Homo Sapiens, then that would be around 2 million years ago, but the predecessors of Homo sapiens could also be considered 'people,' so then you'd have to determine at what point they came into existence.
Answer:
<em>D=25 units</em>
Step-by-step explanation:
<u>Distance Between Points In The Plane
</u>
Given two points P(a,b) T(c,d), the distance between PQ is given by
The given points are P(-10,15) and T(15,15). We can see they have the same value of y, so the line between them is horizontal. The distance can be easier calculated by just subtracting the values of their x-coordinates, but let's follow the formula
D=25
