Question

Marcus is doing an science experiment in which he measures the rate at which bacteria multiply.Every 15 seconds, the bacteria double in number.If there are 10 bacteria now, how many will there be in 2 minutes?

Answer 1

Explanation:

If we calculate so there are 120 sec in 2 min

So we will divide 120 by 15 = 8

It means they will be doubled 8 times

So if bacteria are now 10 so 10 × 8 = 80

There will be 80 bacteria in 2 min
