Question

3. What is the shortest possible time in which a bacterium could travel a distance of 84. cm across a Petri dish

at a constant speed of 3.5 mm/s? *(answer in cm/s)
whats the answer in cm/s

Answer 1

240 s

Step-by-step explanation:

distance = 84 cm

speed = 3.5 mm/s (0.35cm/s)

but speed = distance/time

hence the shortest time taken = distance/speed

= 84/0.35 = 240s
