Calculating Average Speed

Front

What is average speed?

Back

Average speed is the total distance traveled divided by the total time taken.

Front

What is the formula to calculate average speed?

Back

Average speed = Total distance / Total time.

Front

Which unit is NOT used to measure distance?

Back

Minutes are NOT a unit of measurement for distance.

Front

If a car travels 120 miles in 2 hours, what is its average speed?

Back

Average speed = 120 miles / 2 hours = 60 mph.

Front

On which axis is distance plotted in a distance-time graph?

Back

Distance is plotted on the Y-axis.

Front

On which axis is time plotted in a distance-time graph?

Back

Time is plotted on the X-axis.

Front

What is the average speed of a runner who completes a 5-mile race in 50 minutes?

Back

Average speed = 5 miles / (50/60) hours = 6 mph.

Front

If a cyclist travels 30 kilometers in 1.5 hours, what is their average speed?

Back

Average speed = 30 km / 1.5 hours = 20 km/h.

Front

What does it mean if an object has a constant speed?

Back

It means the object covers equal distances in equal intervals of time.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).
