Answer:
<em>Andrew's dog's speed was 1.89 m/s</em>
Explanation:
<u>Motion at Constant Speed</u>
An object is said to travel at constant speed if the ratio of the distance traveled by the time taken is constant.
This can be written as the formula below:
Where
v = Speed of the object
d = Distance traveled
t = Time taken to travel d.
Andrew's dog run a distance of d=17 meters in a time of t=9 seconds, thus its speed was;
v = 1.89 m/s
Andrew's dog's speed was 1.89 m/s
