The average velocity of the car is 37.27 km/h.

The given parameters;

  • Initial displacement of the car, x = 100 km
  • Time of motion, t = 2 hours
  • Final displacement of the car, y = 50 km
  • time of motion, t = 1 hour

The average velocity of the car is calculated as follows;

[tex]average \ velocity = \frac{Total \ displacement}{Total \ time}[/tex]

The total displacement of the car is calculated as follows;

[tex]d = \sqrt{x^2 + y^2} \\\\d = \sqrt{100^2 \ + \ 50^2} \\\\d = 111.803 \ km[/tex]

The average velocity of the car is calculated as follows;

[tex]v = \frac{111.803}{3} \\\\v = 37.27 \ km/h[/tex]
