Question 41258: I need some help on this problem.
A virus scanning program is checking every file for viruses. It has completed checking 40% of the files in 300 seconds. How long should it take to check all the files?
Thanks,

300 divided by 40=
7.5
so it takes it 7.5 seconds to do 1%
so 60 x 7.5=
450 seconds to scan 60%
so add 450 to 300
750 seconds to scan all the viruses in total.
