Question

1. if you know the distance traveled and the amount of time it took, speed may be calculated by: a. dividing time by distance. b. multiplying time by distance. c. dividing distance by time. d. multiplying distance squared by time. 11. a measured quantity that is described by stating a size and a direction is called a: a. scalar. b. magnitude. c. vector. d. victim.

Explanation:

18.

The formula for speed is \(v=\frac{d}{t}\), where \(v\) is speed, \(d\) is distance, and \(t\) is time. This means speed is calculated by dividing distance by time.

A scalar has only magnitude (size). A vector has both magnitude (size) and direction. Magnitude is just the size part of a quantity. "Victim" is not a relevant term in this context.

Answer:

C. dividing distance by time.
