Question

A Life guard at position L spots a swimmer in trouble at one corner of the pool, S. She runs down the length of the pool to position P, and then dives and swims a distance d from P to S.

a) Show that the swimming distance is given by the relation d=wsecx
b) If L=2w, determine the range of values that x may take on, given that P can be anywhere along the length of the pool.

Answer 1

do you have a diagram attached with this problem ?

Answer 2

That's the picture

Answer 3

x
is the angle of S

Answer 4

you want to show `d = wsecx`

so what is `x` in the diagram ?

Answer 5

angle measure of S
