Answer:
Second!
Explanation:
speed and velocity are both measured using the same units.The S.I unit of distance and displacement is the meter. The S.I unit of time is the second. The S.I unit of speed and velocity is the ratio of two-the meter per second!
I hope it's helpful!
Answer:
metre per second
Speed has the dimensions of distance divided by time. The SI unit of speed is the metre per second, but the most common unit of speed in everyday usage is the kilometre per hour or, in the US and the UK, miles per hour.

What role have nitrates and phosphates played in damaging Muddy Creek?
Answer:
Nitrates and phosphates lead to eutrophication and anoxia in the creek which caused aquatic animals to die and damaged the creek.
Explanation:
Nitrates (NO3-) are chemical compounds that contain nitrogen and oxygen molecules. They are salts that are commonly found in fertilizers and are soluble in water. Phosphates are also compounds that are used in agricultural processes.
Nitrates and phosphate found in water are usually from plants that have been washed off by rain water and also from vehicles' exhaust.
When there are abnormally high levels of nitrates and phosphates in water, it becomes difficult for aquatic animals to survive. In bodies of water, the nitrates and phosphates become sources of food to algae and other plants, this causes them to become over stimulated, and lead to Eutrophication (a high concentration of nutrients) and Anoxia (lack of oxygen).
This causes the fishes to run out of oxygen and die. Then the water begins to change color (milky white or green), give off an offensive odor and gradually turns into a swamp and eventually a meadow
