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
