A strain of bacteria undergoes fission every 30 minutes. How long would it take 10 bacteria to increase 640 bacteria?
ale4655 [162]

Answer:

A) 3hrs

Step-by-step explanation:

Fission is the action of dividing or splitting something into two or more parts.

So, we're going to continuously multiply our answers by 2 until we get 360

10 x 2 = 20   30min

20 x 2 = 40   1hr

40 x 2 = 80   1hr 30min

80 x 2 = 160   2hrs

160 x 2 = 320   2hrs 30min

320 x 2 = 630   3hrs
