Question

Scooby doo starts running from point P to Q on a straight line joining them in 100 seconds. What is his average speed and average velocity ?

Answer 1

$hi \: mate$

$here \: is \: your \: answer$

$let \: the \: distance \: be \: x \: meter(m)$

$average \: speed \: = \frac{total \: distance}{total \: time}$

$total \: distance = x \: m$

$total \: time \: = 100sec.$

$average \: speed \: = \: \frac{x}{100} \: m \: per \: s$

$average \: velocity = \frac{total \: displacement}{total \: time}$

$total \: displacement = x \: m$

$average \: velocity \: = \frac{x}{100} m \: per \: s$

hope it helped
