What is its average speed during this 37 s interval? Answer in units o

In summary, average speed is the total distance traveled divided by the total time taken. It is calculated by dividing the total distance by the total time and can have units such as meters per second, kilometers per hour, and miles per hour. Average speed differs from instantaneous speed, which is the speed at a specific moment, and is used in sports, transportation, and engineering to measure and improve performance and efficiency. Examples of average speed being used in real life include calculating fuel efficiency for cars and measuring the average speed of runners in a race.

1. What is the meaning of "average speed"?

The average speed is the total distance traveled divided by the total time taken.

2. How do you calculate average speed?

Average speed is calculated by dividing the total distance traveled by the total time taken.

3. What are the units for average speed?

The units for average speed can vary depending on the units of distance and time used. Common units include meters per second (m/s), kilometers per hour (km/h), and miles per hour (mph).

4. How is average speed different from instantaneous speed?

Average speed is the overall speed of an object over a certain distance and time, while instantaneous speed is the speed of an object at a specific moment in time.

5. How can average speed be used in real life?

Average speed is used in various fields such as sports, transportation, and engineering to measure and improve performance and efficiency. For example, average speed can be used to calculate the fuel efficiency of a car or the average speed of a runner during a race.
