Answer:
v = 1.5 m/s
Explanation:
Given that,
Distance covered by a person, d = 105 m
Time taken, t = 70 s
We need to find the average speed of the person. We know that the average speed is given by :

So, the average speed of the person is equal to 1.5 m/s.
Chemical reactions. The number of electrons in an atom's outermost valence shell governs its bonding behavior. Therefore, elements whose atoms can have the same number of valance electrons are grouped together in the periodic table of the elements.
