Answer:
250 m/min down the road
Explanation:
Velocity is equivalent to speed but it considers the direction of the object. Velocity is also calculated by dividing the distance travelled by time. Therefore,
where d and t are distance and time respectively. Given that d is given as 350 m and t is 1.4 s then by substitution
and the direction is down the road.
Velocity is 250 m/min down the road
