statement 1 gives us no information regarding start time or end time or rate so not sufficient
statement 2: take total work to be 12. now we know by 2 p.m we do 6 units of work and by 2:20 pm we do 10 units of work. so 4 units of work are done in 20 mins so time required to do remaining 2 units of work= 20/4*2 = 10 mins. so the work will be completed by 2:30. statement 2 is sufficient.
