Question

What is the shortest possible time in which a bacterium could travel a distance of 8.4 cm across a petri dish at a constant speed of 3.5 mm/s?

Answer 1

speed of the bacterium is 3.5 mm/s

`v = 3.5 mm/s`

total distance traveled by bacterium = 8.4 cm

`d = 8.4 cm = 84 mm`

time take to cover the distance

`t = (d)/(v)`

`t = (84)/(3.5) = 24 s`

so it will take 24 s to move this distance
