Concept:To find the end time, add the duration separately in hours and minutes, then convert any extra minutes into hours.Explanation:The match starts at $2{:}20$ p.m.The duration is $1$ hour $50$ minutes.Add the minutes first: $20 + 50 = 70$ minutes.Since $70$ minutes $= 1$ hour $10$ minutes, convert this into $1$ hour and $10$ minutes.Now add the hours: $2 + 1 + 1 = 4$ hours.The remaining part is $10$ minutes.So the ending time is $4$ hours $10$ minutes after noon, which is $4{:}10$ p.m.Answer:Option B: $4{:}10$ p.m.
