1 hour after 2.20 p.m. will be 3.20 p.m.We are then left with $5 0$ minutes to add to the $3 . 2 0$ p.m.If you add 40 minutes to the 20 minutes after the 3 p.m. [ 3.20 p.m.] that will be 1 hour [ 60 minutes make an 1 hour] and at that time the time will be 4 p.m. [ 1 hour after 3.00 p.m.] and the 50 minutes will be left with 10 minutes.10 minutes after 4.00 p.m. is 4.10 p.m.Hence the match will end at 4.10 p.m. ALTERNATIVELYTo add time, add the hours separately and the minutes separately If the minutes is $6 0$ or more, convert to hours and minutes 2.20 p.m. $=2$ hours and 20 minutesAdding 1 hour 50 minutesAdding Hours$2+1=3$Adding Minutes20 minutes +50 minutes $=70$ minutes60 minutes make an hour, hence 70 minutes is 1 hour 10 minutesAdd the 1 hour to the previous sum of the hoursTotal hours $=3+1=4$Minutes left is 10 minutesHence the match ends at 4.10 p.m.
