Question

you are asked to run in a straight line . if you cover a distance of 5m in each second what is your speed and velocity

Answer 1

Speed 5 m/s
And
Velocity 5 m/s
Both are same because body is moving in straight line

Answer 2

$speed = \frac{displacement}{time}$
$and \: velocity = \frac{distance}{time}$
But according to your question the path is straight and also not given information about the destination. So, both are equal and is equals to 5m/sec.
