Question
need help solving this: A boardwalk is parallel to and 210 ft inland from a straight shoreline. A sandy beach lies between the boardwalk and the shoreline. A man is standing on the boardwalk, exactly 750 ft across the sand from his beach umbrella, which is right at the shoreline. The man walks 4 ft/s on the boardwalk and 2 ft/s on the sand. How far should he walk on the boardwalk before veering off onto the sand if he wishes to reach his umbrella in exactly 4 min 45 s?

I redrew the diagram for the two right triangle, solve the equation and the answers are whole numbers.
AD-750
750 ft
Letting
AC-720-x
CE=x
-720
210 ft
boardwalk
AE-720
>The triangle AED is right triangle with hypotenuse AD 750, one of the leg ED 210 but to complete we need
to find AE the other leg of the right triangle using Pythagoream
AE 210-7502
AE² 7502-2102 (750 +210) (750-210)-960-540
AE= √√960-540 = 720, if AC-720-x, then CE-x this will simplify the equations.
so the distance he walks on the sand from point C to D is the hypotenuse of the right triangle ACED whose two legs are x and 210
CD²x²+2102 thus CD-√x²+210²
√x²+2102
then time walking on the sand at 2 ft per second
2
4 f
plus time walking on the boardwalk at
720-x must be 4 minutes 45 seconds or 285 seconds.
