(1) Contestant A ate his cookies at a constant rate of 20 cookies per minute and Contestant B ate her cookies at a constant rate of 15 cookies per minute.
(2) Contestant A is younger than Contestant B.
We have the rate of each contestant, total number of cookies and differential no. of cookies eaten.
We have every info needed to find out total number of cookies eaten by A.

Not helpful. Insufficient.this is how it will work out if you pursue the solution from statement 1...
speed*time of A - speed*time of B = Difference in no. of cookies eaten
Let t=time taken for contest
A ate 80 cookies.
