6. If a car went a distance of 225 kilometers in 4
hours, what is the speed of the car?
a 56.25 km/h
b. 900 km/h
c. 450 km/h
d. 0.0178 km/h

56.25

Explanation:

225/4=56.25

  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
