Practical Mathematics K11Computer Update Problem suggested by Leslie Green

I spot a computer at work which is doing updates.
When I arrive it says '93% complete'.
I immediately start timing the activity and it takes 8 minutes to change to '95% complete'.

Assuming the 'percentage complete' relates directly to time, how much longer will it take to reach '100% complete'?


It could take hours!More than 50 minutesBetween 15 and 50 minutesLess than 15 minutes
