Mrs garcia traveled 15 km in 1 hour. what was her average velocity in km/s?

v= 4.17 km/ s

Explanation:

we apply the uniform motion formula:

v= d/t Formula (1)

Where

v : is the velocity in m/s

d: is the distance in meters (m)

t: is the time in seconds (s)

Equivalence

1 hour = 3600 s

Known data

d=15 km

t = 1 hour = 3600 s

Problem development

We apply the formula (1) for calculate the speed:

v= 15 km/3600 s

v= 4.17 km/ s
