Car A traveled 1200 km in 8 h. Car B traveled 1100 km in 6.5 h. Car C traveled 1300 km in 8.3 h. Which car had the highest average velocity? How long would it have taken the slowest car to travel the same distance as the fastest car?

  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

i don't understand. explain it clearly
