Question

1) Andrew wanted to watch his dog run to see how fast he can to see what 1 point

Answer 1

Answer:

Andrew's dog's speed was 1.89 m/s

Explanation:

Motion at Constant Speed

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:

$\displaystyle v=\frac{d}{t}$

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;

$\displaystyle v=\frac{17}{9}$

v = 1.89 m/s

Andrew's dog's speed was 1.89 m/s
