Question

Marcus is running a science experiment in which he measures the rate at which bacteria multiply. Every 15 seconds the bacteria double in number. If there are 5 bacteria now, how many will there be in 3 minutes? A. 2048 B. 2560 C. 20480 D. 1200

Answer 1

C. 20480

Explanation:

so the equation is (60x3) divided by 15 because there are 3 minutes and 60 seconds in each minute and the bacteria doubles every 15 seconds so when you get your answer (12) that is how many times you will double 5.
