Question 1143544
<br>
Obviously it is the virus, and not some anti-virus, that is spreading exponentially, since nothing is said anywhere else in your statement of the problem about an anti-virus.<br>
The doubling time is 17 minutes, so the population of infected computers is<br>
{{{100(2^(t/17))}}}<br>
where t is the number of minutes after the start.<br>
1 hour (60 minutes): {{{100(2^(60/17))}}}
1 hour 30 minutes (90 minutes): {{{100(2^(90/17))}}}
24 hours (1440 minutes): {{{100(2^(1440/17))}}}<br>
You can do the calculations.
