Chapter 4.5, Problem 66ES
A farmer wants to walk at a constant rate from her bam to a straight river, fill her pail, and carry it to her house in the least time.
(a) Explain how this problem relates to Fermat’s principle and the light-reflection problem in Exercise 64.
(b) Use the result of Exercise 64 to describe geometrically the best path for the farmer to take.
(c) Use part (b) to determine where the farmer should fill her pail if her house and bam are located as in Figure Ex-66.
