we are given
A woman walks due east on the deck of a ship at 4 mi/h.
the ship is moving south at a speed of 24 mi/h
so, firstly, we will draw diagram
so, we have


now, we can use Pythagoras theorem

now, we can plug values
and we get


so,
the speed of the woman relative to the surface of the water is 24.33 mi/h .......Answer

18.19.
First you have to subtract 15 from 100, giving you 85%. You then multiple 85% to the $20, giving you $17. You then add the 7 to 100, giving you 1.07%, then you multiple that to the $17 and you end up with $18.19.
