Question

A runner finishes one lap if the distance from starting point to finish line is 50 m and he finishes the love within one minute what is his average velocity

Answer 1

$$x_1=0;x_2=50m;t_1=0sec;t_2=60sec$$

We know that

Average velocity

$V_{ave}=\frac{x_2-x_1}{t_2-t_1}$

$V_{ave}=\frac{50-0}{60-0}=0.833m/sec$
