Siblings Jason, Kent, and Larry decided to plant some seeds in their garden. They started promptly starting at 1:00pm. With the three of them working together, it should take three hours.At 2:55pm, Kent received a phone call and had to go. Jason and Larry continued to plant seeds.At \(3:00\)pm, Jason hurt his hand and couldn’t continue. Larry decided to finish the job himself on that day. Assume each sibling worked at the same efficiency. When will Larry finish? Please give the answer in the format XX:YY.
+37153 They need a total of 3 man * 3 hours = 9 man hours to finish the job
at 2.55 they have completed ( 1 + 55/60) * 3 = 5.75 man hours 3.25 more to go
now there are two working for 5 /60 hour = 1/6 man hour 3 1/12 to go
at 3:00 it will take Larry 3 1/12 hour to finish = 6:05 pm
