7.7a Speed Review

Front

What is speed?

Back

Speed is the distance traveled per unit of time, typically measured in miles per hour (mph) or kilometers per hour (km/h).

Front

What is the formula for calculating speed?

Back

The formula for speed is s = d/t, where 's' is speed, 'd' is distance, and 't' is time.

Front

What is distance?

Back

Distance is the amount of space between two places, measured in units such as meters, kilometers, miles, etc.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

How do you calculate average speed?

Back

Average speed is calculated by dividing the total distance traveled by the total time taken: Average Speed = Total Distance / Total Time.

Front

If a car travels 60 miles in 2 hours, what is its speed?

Back

Speed = Distance / Time = 60 miles / 2 hours = 30 miles/hour.

Front

What two measurements do you need to calculate speed?

Back

You need to know the distance traveled and the time taken to travel that distance.

Front

What is the formula to calculate distance?

Back

The formula to calculate distance is d = s x t, where 'd' is distance, 's' is speed, and 't' is time.

Front

If a runner completes a 10 km race in 50 minutes, what is their average speed in km/h?

Back

Average Speed = Total Distance / Total Time = 10 km / (50/60) hours = 12 km/h.

Front

What is the unit of speed in the metric system?

Back

The unit of speed in the metric system is kilometers per hour (km/h).
