What was the velocity of the student at $9$ seconds?
$D i s t a n c e / m$ $0$ $1$ $2$ $3$ $4$ $5$ $6$ $6$ $6$ $3$ $0$
$T i m e / s$ $0$ $1$ $2$ $3$ $4$ $5$ $6$ $7$ $8$ $9$ $10$

Solution

formula,

speed = distance / time

$V = \frac{s}{t}$

$V$ at $t = 9 s e c$

at $t = 9 s e c \to s = 3 m$ (given)

$∴ V = \frac{3}{9} = 0.333 m / s$
