Front

What is speed?

Back

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

Front

How do you calculate speed?

Back

Speed (S) is calculated using the formula: S = D/T, where D is distance and T is time.

Front

What is the unit of speed?

Back

The unit of speed can be kilometers per hour (km/hr) or meters per second (m/s).

How long does Bart run if he covers 5,000 meters at 6 m/s?

Back

Bart runs for 833.3 seconds.

Front

What is the formula to find distance?

Back

Distance (D) can be found using the formula: D = S x T, where S is speed and T is time.

Front

What is the average speed if John bicycles 6 kilometers in 90 minutes?

Back

John's average speed is 4 km/hr.

Front

What is the correct equation to calculate speed?

Back

The correct equation to calculate speed is: Speed = Distance / Time.

Front

If a runner completes a 400-meter track in 50 seconds, what is their speed?

Back

Speed = 400 meters / 50 seconds = 8 m/s.

Front

What does it mean if an object is moving at a constant speed?

Back

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