John went on a mission that was supposed to take 5 days.  Instead it took 60% longer.  He then had to go on a second mission which took 3 days.  How long was he on missions?
The first mission took 5*.6=<<5*.6=3>>3 days longer than anticipated
So it took 5+3=<<5+3=8>>8 days
That means the two missions took 8+3=<<8+3=11>>11 days
