Hello, ineedhelplz!

The diagram and description are not correct.

I think I've corrected them,

Find the value of x (on the right vertical side) to find the minimum time to travel to the top right corner of the "forest".

The forest can be travelled through at 3 km/h and the "clear" area can be travelled through at 5 km/h.

The graphic shows 2 km at the bottom and x km on the right side.

A man wants to get from A to B in the least amount of time.Code:* B - | : |d-x: | : *P : * | d * | : * |x : * | : * | : A * - - - - - - - - *C - : - - - 2 - - - :

He walks through the "forest" from point A to point P

. . then walks in the "clear" from point P to point B.

Let

He walks distance at 3 km/hr.

. . This takes hours.

He walks distance at 5 km/hr.

., . This takes hours.

The total time is: .

Andis the function we must minimize.,that
