No. It is a speed (a scalar) but not a velocity (a vector).
Miles per hour and seconds are units of measurement of speed and time respectively, which are scalar quantities.
It is a scalar quantity unless you define direction, then it becomes a vector quantity.
scalar
Unfortunately this question can't be answered. The reason for this, is because there is no stated direction for the 'velocity' therefore it isn't a vector quantity, it's scalar.
(55 miles per hour) is a scalar. (55 miles per hour heading north) is a vector.
No. It is a speed (a scalar) but not a velocity (a vector).
Traveling 60 miles per hour is a scalar quantity. Scalars only have magnitude and no direction, whereas vectors have both magnitude and direction. In this case, the speed of 60 miles per hour is the magnitude of the quantity without specifying a direction.
A scalar is a magnitude only (...I am driving at 60 miles per hour), while a vector is a magnitude and direction (...I am driving at 60 miles per hour, heading east).

No, thirty meters per hour is a scalar quantity because it only has magnitude (30 meters) and does not have direction. A vector quantity would include both magnitude and direction, such as 30 meters per hour due east.
TRUE. However, if you said '60 miles per hour in a northerly direction' , then that is a vector quantity. because it has direction.
No, mph (miles per hour) is a scalar quantity, not a vector quantity. Scalar quantities have magnitude only, while vector quantities have both magnitude and direction. In the case of mph, only the speed or magnitude is specified, not the direction.
scalar
There is no such thing as 'scalar velocity'. Velocity is a vector, always. A quantity that tells how fast an object is moving but doesn't tell in which direction it's moving is a scalar. That quantity is called "speed". Three examples are: -- Driving 30 miles per hour. -- Running 8 miles per hour. -- Sliding 15 feet per second.
Adding two vectors typically results in another vector quantity, not a scalar. The resultant vector is found using vector addition, which considers both the magnitude and direction of the original vectors.
