Marie made a clepsydra to measure time. In order to check the accuracy of the instrument, it places 1 L of water in the upper container of the clepsydra. Then she observes the amount of water flowing into the lower container as a function of time. The graph opposite represents the first moments of the experience.
1. How much water is found in the lower container of the clepsydra after a minute?
2. How much water should be found in the lower container of the clepsydra after ten minutes? Justify.
3. We call / the function that gives the amount of water in the lower part of the clepsydra as a function of time.
* Is this function a linear function? Justify.
* Then give the expression of this function / .
4) After how long will the upper container of the clepsydra be empty? Justify.
