Calculating Speed

Front

What is speed?

Back

Speed is the distance traveled per unit of time, typically measured in kilometers per hour (km/h) or meters per second (m/s).

Front

How do you calculate average speed?

Back

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

Front

If a car travels 150 km in 3 hours, what is its average speed?

Back

50 km/h

Front

What is the unit of speed?

Back

The unit of speed is commonly kilometers per hour (km/h) or meters per second (m/s).

Front

What does a constant speed graph look like?

Back

A constant speed graph is a straight line that shows equal distance covered in equal time intervals.

Front

If a runner completes a 400 m race in 50 seconds, what is their speed?

Back

Speed = Distance / Time = 400 m / 50 s = 8 m/s.

Front

What is the formula for calculating distance?

Back

Distance = Speed x Time.

Front

If a cyclist travels at a speed of 15 km/h for 2 hours, how far do they travel?

Back

Distance = Speed x Time = 15 km/h x 2 h = 30 km.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity per unit of time, indicating how quickly an object speeds up or slows down.

Front

If a snail moves at 0.3 m/min, how far does it travel in 10 minutes?

Back

Distance = Speed x Time = 0.3 m/min x 10 min = 3 m.
