Question

A ship travels north at 15 km/h for 5 h. What is the ship's displacement in km?

Answer 1

Answer:

Displacement, d = 75 km

Explanation:

Given that :

The speed of the ship is 15 km/h. It travels for 5 h.

To find :

The displacement of the ship

Solve :

Let d is the displacement of the ship. It can be calculated using the definition of velocity. The total displacement per unit time is called the velocity of an object.

$v=\dfrac{d}{t}$

On rearranging,

$d=v\times t$

$d=15\ km/h\times 5\ h$

d = 75 km

Therefore, the ship's displacement is 75 km.

Answer 2

So you would do 15*5 to get 75
