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.
Velocity is speed and its direction. "30 miles per hour" is a speed. "30 miles per hour north" is a velocity". "30 miles per hour north" and "30 miles per hour south" are identical speeds but different velocities.
To find the unit rate, divide the quantity of one item by the quantity of another item, ensuring that the second quantity is set to one. For example, if you have 60 miles driven in 3 hours, you would divide 60 miles by 3 hours to find the rate per hour, resulting in 20 miles per hour. This method can be used with any two related quantities to express the rate per one unit of the second quantity.

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 = 24.85 miles per hour.
