Answer:
A) 30h
B) Scalar quantity
Explanation:
Part A
[Note: v represents speed, d represents distance, and t represents time]
Given:
[tex]d = 600 km[/tex]
[tex]v = 20 km/h[/tex]
Required:
[tex]t = ?[/tex]
Analysis:
[tex]v = \frac{d}{t} \\t = \frac{d}{v}[/tex]
Solution:
[tex]t = \frac{d}{v} \\t = \frac{600 km}{20 km/h} \\t = 30 h[/tex]
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.
