hector went to the music store by heading due south at 3 m/s, then turning west and continuing at the same speed for another three blocks. which of the following is true at hectors velocity

Hector's velocity is a vector quantity that represents both the speed and direction of his motion. From the given information, we can determine the following:

1. Hector went due south at 3 m/s: This means his initial velocity was in the south direction with a speed of 3 m/s.

2. Hector turned west and continued at the same speed for another three blocks: This means he changed his direction from south to west, but maintained the same speed of 3 m/s.

Based on these statements, we can conclude that the velocity vector for Hector remains constant in magnitude (3 m/s), but its direction changes from due south to due west. Therefore, the following statement is true at Hector's velocity:

- The magnitude (speed) of Hector's velocity remains constant at 3 m/s.

- The direction of Hector's velocity changes from south to west.
