Although playing chess doesn't intrigue John, he agreed to play a few games with Anthony. Anthony has a real knack for the game and easily defeated John every time they played. The first game lasted one-fourth of an hour. The second game took a third of an hour and the third game was over in one and one-fifth hours. How long did it take Anthony to defeat John all three times?

1/4 hour  =  15 min 

1/3 hour  =  20 min 

1 hour     =  60 min 

1/5 hour  =  12 min   =>  total 107 min or 1 hour 47 min

1st game -> 1/4 hr 2nd game -> 1/3 hr

3rd game -> 1 1/5 hr

1/4 + 1/3 + 1 1/5 = 1/4 + 1/3 + 6/5

                           = 107/60 or 1 hour and 47 minutes 

It took 1 hour and 47 minutes long for Anthony to defeat John in all three games
