Ms garcia walks from taco palenque to the post office in 5 minutes. taco palenque is located 0.30 km from the post office. what was her speed?

v= 1 m/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 km =1000m

1 minute= 60 s

Known data

d=0.30 km = 0.3 *1000m= 300m

5 minutes = 5*60 s= 300 s

Problem development

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

v= 300m/300 s

v= 1 m/s

see earlier

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is
