It is a measurement that doesn't have direction, such as distance. A vector has direction
Vector is NOT a scalar. The two (vector and scalar) are different things. A vector is a quantity (measurement) in which a direction is important. A scalar is a quantity in which a direction is NOT important.
A scalar in physical science is a unit measurement in a single direction. For example, you can have a mass scalar, which is 1kg to the right, or you can have an energy scalar, which is 1J forwards.

It does not require direction, so it's a scalar quantity.
No, it's a scalar measurement because it has magnitude only. A vector measurement has both a magnitude and a direction.

Scalar contains only the magnitude but Vector contains the magnitude and direction.
Any measurement for which only a magnitude is required, but not a direction. The opposite of a vector: a measurement for which a direction IS relevant.
Miles per hour and seconds are units of measurement of speed and time respectively, which are scalar quantities.
