Answer:
d = 19.5 m
Step-by-step explanation:
Conceptual analysis
The average speed is defined as the relationship between the displacement that a body made and the total time it took to perform it.
The formula that will allow you to calculate the average speed is:
v= d/t Formula (1)
v= average speed measured in m/s
d= displacement measured in m.
t= time interval measured in s.
Known data
v= 6.5 m/s
t= 3 s
Problem development
We replace data in the formula (1) to calculate the distance (d) :
v= d/t
6.5 m/s = d / 3 s
(6.5 m/s)*( 3 s ) = d
d = 19.5 m
