Question

One of the reasons bacteria can be so deadly is because they multiply very quickly. E. coli has a doubling time of around 15 minutes. This means that if 100 bacteria are left alone for 2 hours, they will multiply to become:

Answer 1

the amount of e. coli is now 25,600

Step-by-step explanation:

2 hours = 120 minutes

120/15 = 8

i dont know how to write down this next part so im gonna just do it slowly

1. 100 x 2 = 200
2. 200 x 2 = 400
3. 400 x 2 = 800
4. 800 x 2 = 1600
5. 1600 x 2 = 3200
6. 3200 x 2 = 6400
7. 6400 x 2 = 12800
8. 12800 x 2 = 25600
