Willis has noticed that when time has been one of the variables analyzed by a scatterplot he has been the independent variable. he has hypothesized that time can never be a dependent variables

Option 3 is right

Step-by-step explanation:

Given that Willis has noticed that when time is one of the variable then time has to be independent variable.

Time cannot be a dependent variable and the change of time determines the change of dependent variable.

In the scatter plot always independent variable is marked on horizontal axis and dependent variable on y axis.

But in the given graph contrary to the above, time is marked on y axis which shows that distance is independent and time is dependent.

i.e. It invalidates his hypothesis because it is possible for the time to take a trip depends on the distance traveled during the trip.

The answer is the third option: "It invalidates his hypothesis because it is possible for the time a trip takes to depend on the distance that is traveled during the trip."
