Question

tempo means the speed of the:

car

Explanation:

In music, tempo specifically refers to the speed of the beat. It determines how fast or slow a piece of music is played. A car's speed is just a general speed measurement not related to musical terms. A symphony is a large - scale musical composition, not a measure of speed. The term tempo is directly associated with the speed at which the beats occur in a musical piece.
