Answer 2

There are two types of 'quantities' namely: scalar and vector

A 'vector' is a quantity that has both magnitude and direction whereas a 'scalar' has only magnitude.

Magnitude is a measure or the size of the quantity or object.

In the given example of the vector: '75 mph to the north'

Magnitude is the number 75 mph

Direction is north
