Question

Hi, I need some help with my precal homework.

Answer 1

A man stands at a point A on the bank of a straight river, 2 mi wide. To reach point B, L = 11 mi downstream on the opposite bank, he first rows his boat to point P on the opposite bank and then walks the remaining distance x to B, as shown in the figure. He can row at a speed of 2 mi/h and walk at a speed of 5 mi/h.

(a) Find a function that models the time needed for the trip.
T(x) =

(b) Where should he land so that he reaches B as soon as possible? (Round your answer to two decimal places.)
miles from point B

Answer 2

"... walks the remaining distance x to B, as \(\color{red}{\text{shown in the figure}}\). He can row at a..."

if we had that "figure", it'd help
