Question

If one computer takes 3.5 days to scan and one takes 4.5 days to scan how long will it take for them to scan again at the same time

Answer 1

if they both start scanning at the same time it should take 4.5 days to finish scanning both of whatever is being scanned?

unless youre asking how long will it take for them to finish scanning at the same time, in that case i think it would take 31.5 days
