Question

which of the following would you need to measure average speed? (check all that apply) radar gun stopwatch measuring stick speedometer

Explanation:

To find average speed, we use the formula \( \text{Average Speed} = \frac{\text{Total Distance}}{\text{Total Time}} \). A stopwatch is used to measure the total time taken (for the "time" part of the formula). A measuring stick can be used to measure the total distance covered (for the "distance" part of the formula). A radar gun and a speedometer typically measure instantaneous speed (speed at a specific moment) rather than average speed over a period/distance.

Answer:

B. Stopwatch, C. Measuring Stick
