a paramecium is a single-celled organism that lives in ponds. it travels at a rate of 2,000 micrometers per second. what is the speed of the paramecium in meters per hour? (hint: look at the first tile to see how many significant digits are in the value.)



Answer :

When a paramecium travels at the rate of 2,000 micrometers per second. Then its speed in meters per hour will be 7.2 m/sec.

Paramecium is a eukaryotic protozoan belonging to the Kingdom Protista. It is unicellular organism with cilia all over its body. They are abundantly found in fresh-water. The use of paramecium can be found in carbon cycle.

According to the question,

Speed of paramecium = 2,000 micrometers (μm) per second

1 μm = 10 ⁻⁶ meter

Also, 1 second = 1/3600 hour

Therefore, the speed of paramecium in m/hour will be

speed = [2000 × 10 ⁻⁶] / [1/3600]

Therefore, speed = 7.2 m/hour
