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
