it's a vector quantity because it is aquantity which only shows the speed of the vehicle but scaler shows direction also.
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).
60 mph is a scalar.60 mph north is a vector.
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, it's a scalar quantity. ;)

TRUE. However, if you said '60 miles per hour in a northerly direction' , then that is a vector quantity. because it has direction.
scalar
Velocity is a vector quantity, meaning that it has both a magnitude and a direction. Mass, on the other hand, is a scalar quantity; it has a magnitude only. Velocity is measured in units of distance divided by time; for example, meters per second or 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.
North at 45 miles per hour. A vector has a direction and a magnitude.
