A ship is moving West at a velocity of 30 mph and a person is on deck walking EAST at a velocity of 5 mph. To the observer on shore, what is the relative speed of the person walking on the ship’s deck?

looks like 25 mph West to me

To find the relative speed of the person walking on the ship's deck as observed from the shore, we need to consider the velocities of the ship and the person relative to the shore.

Given:
Ship's velocity = 30 mph (westward)
Person's velocity = 5 mph (eastward)

To find the relative speed, we need to find the difference between the velocities of the ship and the person. Since they are moving in opposite directions, we need to add their velocities to find the relative speed.

Relative speed = |velocity of the ship - velocity of the person|

Substituting the given values:
Relative speed = |30 mph - 5 mph|
Relative speed = |25 mph|

Therefore, the relative speed of the person walking on the ship's deck as observed from the shore is 25 mph.
