What is speed?

Back

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

Front

How do you calculate speed?

Back

Speed = Distance ÷ Time.

Front

What is distance?

Back

Distance is the total length of the path traveled by an object, measured in units such as meters (m) or kilometers (km).

Front

What is time in the context of speed, distance, and time calculations?

Back

Time is the duration taken to travel a certain distance, measured in seconds (s), minutes (min), or hours (hr).

Front

If an object travels 26 centimeters per second, how do you convert this to meters per minute?

Back

To convert cm/s to m/min, multiply by 60 (seconds in a minute) and divide by 100 (cm in a meter). 26 cm/s = 15.6 m/min.

Front

How do you find the average speed of an object?

Back

Average speed is calculated by dividing the total distance traveled by the total time taken.

Front

If a car travels 4 meters in 2 seconds, what is its speed?

Back

Speed = Distance ÷ Time = 4 m ÷ 2 s = 2 m/s.

Front

What is a unit rate?

Back

A unit rate is a comparison of two different quantities when they are combined together, expressed as a quantity per 1 unit of another quantity.

Front

How do you express 400 meters in 5 minutes as a unit rate?

Back

Unit rate = 400 m ÷ 5 min = 80 m/min.

Front

If Sally is traveling at 18 m/hr and covers 9 m, how do you find the time taken?

Back

Time = Distance ÷ Speed = 9 m ÷ 18 m/hr = 0.5 hr.
