    no

    Step-by-step explanation:

    Chris' Ratio/Rate : 5cookies:2minutes

    Find the unit rate: cookies per minute

    5/2=2.5

    Chris eats 2.5 cookies per minute

    Now, to find out if he would finish all 19 of them in 7 minutes, multiply 2.5 by 7.

    2.5 x 7 = 17.5

    So the answer would be No, Chris could not finish all of the cookies in time.

    he would have 1.5 cookies left over
