physics !!!!!!!!!!!!!!!!!?
so i'm confused on how to find relative velocity. i have this problem: A person going for a morning jog on the deck of a cruise ship is running toward the bow(front) of the ship at 2.2 m/s while the ship is moving ahead at 7.5 m/s. What is the velocity of the jogger relative to the water? Later, the jogger is moving toward the stern (rear) of the ship. What is the jogger's velocity relative to the water now?
Answers are mucho appreciated :)

velocity is a vector (a value and a direction),
you should assume a direction as positive at first, lets take front direction as positive in this example:
V_person relative to water = V_person relative to boat + V_boat relative to water
then in first case: V_person relative to water = 2.2+ 7.5=9.7 m/s
in second case : V_person relative to water= -2.2 + 7.5= 5.3 m/s
Yes I agree with what's been said so far
