6.8C Mini Flashcard #2

Front

What is average speed?

Back

Average speed is the total distance traveled divided by the total time taken. It is usually expressed in units such as meters per second (m/s) or kilometers per hour (km/h).

Front

How do you calculate average speed?

Back

Average speed = Total Distance / Total Time.

Front

If a cart travels 84 meters in 28 seconds, what is its average speed?

Back

3.0 m/s (84 m / 28 s = 3.0 m/s).

Front

What is the formula to convert km/h to m/s?

Back

To convert km/h to m/s, divide the speed by 3.6.

Front

How do you convert km/min to m/s?

Back

To convert km/min to m/s, multiply the speed by 1000 and then divide by 60.

Front

If a rocket reaches 825 km in 75 seconds, what is its average speed in km/min?

Back

660 km/min (825 km / (75 s / 60 s/min)).

Front

What is the average speed of a car that travels 160 km in 2 hours?

Back

80 km/h (160 km / 2 h = 80 km/h).

Front

How do you find the average speed of an object in a lab experiment?

Back

Conduct multiple trials, record the distance and time for each trial, then calculate the average speed using the formula: Average Speed = Total Distance / Total Time.

Front

If a toy car travels 2 meters in 11 seconds, what is its average speed?

Back

0.18 m/s (2 m / 11 s).

Front

What is the average speed of a toy car that travels 240 cm in one minute?

Back

4 centimeters per second (240 cm / 60 s = 4 cm/s).
