The dimensions are [L][T-1]
where
L = length,
T = time.
(55 miles per hour) is a scalar. (55 miles per hour heading north) is a vector.
The physical quantity measured by a speedometer is speed, which is the rate at which an object is moving. It typically indicates the speed of a vehicle in kilometers per hour or miles per hour.
Average speed.
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.
TRUE. However, if you said '60 miles per hour in a northerly direction' , then that is a vector quantity. because it has direction.
Speed is a scalar quantity that measures the rate of motion, while velocity is a vector quantity that includes both speed and direction. Speed only tells you how fast an object is moving, but velocity tells you how fast it's moving and in which direction.

50 miles per hour.
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.
About 55 miles per hour.
40 kilometers per hour is approximately equal to 24.85 miles per hour.
35 miles per hour = 56.32704 kilometers per hour
