A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.

In this problem, to find who hiked at the fastest rate, we have to find the proportion of distance by time, hence:

Ellen: 6 mi/3h = 2 mi/h.

Donald: 2 mi/ 4 h = 0.5 mi/h.

Lars: 6 mi/4 h = 1.5 mi/h.

The highest rate was of 2, hence the person who hiked at the fastest rate was Ellen.
