Answer:
Independent variable- Number of water bottles preparing
Dependant variable- Number of hours she expects to be on the course
Step-by-step explanation:
The independent variable is the one you change. Lara in this case is changing the number of water bottles, she is preparing them. The dependant variable you can think of as the effect- depending on how many she prepares will influence the number of hours on the course.
On a graph, remember that the independent variable is on the bottom.
Hope this helps!
