Answer 1

average speed is v = $\frac{t o t a l d i s t a n c e}{t o t a l t i m e}$
total distance is 40m and total time is 8sec
$v = \frac{4 0}{8} = 5 m s^{- 1}$
hence the B option is correct

Answer 2

average speed is v =

\frac{t o t a l d i s t a n c e}{t o t a l t i m e}

total distance is 40m and total time is 8sec

v = \frac{4 0}{8} = 5 m s^{- 1}

hence the B option is correct

The position (X)-time (t) graph for a particle moving along a straight line is shown in figure. The average speed of particle in time interval $t = 0$ to $t = 8 s$ is

$Z e r o$

$5 m / s$

$7.5 m / s$

$9.7 m / s$

average speed is v = $\frac{t o t a l d i s t a n c e}{t o t a l t i m e}$
total distance is 40m and total time is 8sec
$v = \frac{4 0}{8} = 5 m s^{- 1}$
hence the B option is correct
