Question

What is the shortest possible time in which a bacterium to travel distance of 8.4cm across a Petri dish at a constant velocity of 1.2 cm/s

Answer 1

`\boxed{\sf Shortest \ possible \ time = 7 \ seconds}`

Given:

Distance travelled (s) = 8.4 cm

velocity (v) = 1.2 cm/s

To Find:

Shortest possible time (t) in which a bacterium travel a distance 8.4 cm across a Petri Dish

Step-by-step explanation:

`\boxed{ \bold{\sf Time \ (t) = (Distance \ travelled \ (s))/(Velocity \ (v))}}`

Substituting values of Distance travelled (s) & Velocity (v) in the equation:

`\sf \implies t = (8.4)/(1.2)`

`\sf \implies t = \frac{7 * \cancel{1.2}}{ \cancel{1.2}}`

`\sf \implies t = 7 \: s`
