    Time and speed is a pair of scalar quantities.

    Explanation:

    Scalar quantities are known to have only magnitude and don't have a direction. Some examples of scalar quantities are mass, length, temperature etc. In contrast a vector quantity is known to have a definite magnitude as well as a well defined direction.

    Force, displacement, velocity etc are some common vector quantities. The value of a vector quantity can be taken positive or negative depending on the direction of the vector. Vectors are represented by vector diagrams.
