we know,
velocity is the rate of change of position of an object. or you can say that velocity is the change in position of particle per unit time.
instantaneous velocity is
it means, if we draw graph position v/s time. slope of graph indicates velocity.
how to find slope :- if two point and are given in a straight line, then slope of straight line is given by
here, two points (4,50) and (0,20) are given
then,slope of graph = (50 - 20)/(4 - 0) = 30/4 = 7.5
hence, velocity of the object = 7.5 m/s

Answer:
Explanation:
As we know, slope of position(x)-time(t) graph give velocity (v)
Slope (m) = X 2-X1 / t2-t1
m = 50-20 /4-0
m =7.5m/s
