If a runner travels 50 m in 5 sec, his average speed is what?

If an object's average speed is 5 m/s, it will move 5 m in 1 s.

Explanation:

10m/s

Explanation:

average speed = distance covered / time taken

average speed = 50 m / 5 sec

average speed = 10m/s

0.19 m/s and 0.45 m/s

  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
