Question

PLEASE ANSWER!!!

a ship sails a distance of 600 km at a speed of 20km/h.
A) for what amount of time was the ship sailing?
B) is this a scalar quantity or a vector quantity?

Answer 1

A) 30h

B) Scalar quantity

Step-by-step explanation:

Part A

[Note: v represents speed, d represents distance, and t represents time]

Given:

`d = 600 km`

`v = 20 km/h`

Required:

`t = ?`

Analysis:

`v = (d)/(t) \\t = (d)/(v)`

Solution:

`t = (d)/(v) \\t = (600 km)/(20 km/h) \\t = 30 h`

Statement:

Therefore, the ship was sailing for 30 hours.

Part B

This is a scalar quantity because time only has magnitude and can never be given direction so it can never be a vector quantity.
