If it takes ashley 3 seconds to run from the batters box to first base at an average speed of 6.5 meters per second, what is the distance she covers in that time?

d = 19.5 m

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
