Question

The population of bacteria in a petri dish doubles every 12 h. the population of the bacteria is initially 500 organisms. how long will it take for the population of the bacteria to reach 800?

Answer 1

Answer: 0.096 hours which when multiplied gives you 5 hours

Explanation: Initially the population is 500 organisms which is the 0 hour,then do the following calculation:

800 x 0.06 ÷ 500 = 0.096

The 0.06 comes from:

1000x ÷ (500x12) = 0.06
