i have the followin question and i am not sure how to solve it :

The table of data below was produced by students who did the leaking-faucet experiment. The measuring container they used held only 100 milliliters. If the students had continued their experiment, after how many seconds would the measuring container have overflowed?

Time: 10 20 30 40 50 60 70

Water loss (milliliters) 2 5 8.5 11.5 14 16.5 19.5

thank you in advance for your help.
