Concept:
If every element of a set D is an element of set E, then D is the subset of E.
e.g
D={1,2,3}, E={1,2,3,4}
As all the elements of D are in E, so D is the subset of E.
Now the intersection of two sets D and E is the set of all elements which belong to both D and E.
As, in our example the set D={1,2,3} is the intersection of set D and set E.
From the above discussion, it is proved that <span>If set D is not the empty set but is a subset of set E then
</span> <span>D ∩ E = D is the true answer.</span>
Answer:
si yo lo sé tú también cierto
The best way to interpret this question is that the X is equals how far the destination is and the person rate in going home is 25mph. So the needed variable are X and the Speed. Speed has a unit of m/h and the distance is m so the answer should be x/25
