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?
assistant
How many days did the first mission take? ** The first mission took 5*.6=<<5*.6=3>>3 days longer than anticipated
How many days did the first mission take? ** So it took 5+3=<<5+3=8>>8 days
How many days did the first and second missions take? ** That means the two missions took 8+3=<<8+3=11>>11 days
