A bacterial culture starts with 3000 bacteria and increases to 48,000 after 3 hours, find the doubling time:
Answers
Answer 1
Answer:
4
3000 times 2 = 6000
6000 times 2 = 12000
12000 times 2 = 24000
24000 times 2 = 48000
3000 times 2 = 6000
6000 times 2 = 12000
12000 times 2 = 24000
24000 times 2 = 48000
