Question

What does the expression 75 meters per second southeast best describe?

Answer 1

The expression “75 meters per second southeast” best describes velocity.

The beginning of the expression is providing the amount of speed of something so right away you might think that the answer is speed. Then, you read ‘southeast’ and notice the expression is also providing the direction. So, this might cause you to debate whether the answer is speed or distance, but the answer would be both. The term for an expression that is giving the speed of something and the given direction is “velocity."
