What is the shortes possible time in which a bacterium could travel a distance of 8.4 cm across a Petri dish at a constant speed of 3.5mm/s?
8.4 cm = 84 mm
84/3.5 = 24 seconds
To find the shortest possible time for a bacterium to travel a distance of 8.4 cm across a Petri dish at a constant speed of 3.5 mm/s, we can use the formula:
Time = Distance / Speed
First, let's convert 8.4 cm to mm:
8.4 cm = 8.4 cm * 10 mm/cm = 84 mm
Now we can plug in the values into the formula:
Time = 84 mm / 3.5 mm/s
Dividing 84 mm by 3.5 mm/s gives us:
Time = 24 seconds
Therefore, the shortest possible time for the bacterium to travel a distance of 8.4 cm across the Petri dish at a constant speed of 3.5 mm/s is 24 seconds.
