1.2 Flashcard Representing Rates

Front

What is a rate?

Back

A rate is a ratio that compares two different quantities, often expressed as a quantity per unit of time.

Front

How do you calculate distance traveled using a rate?

Back

Distance = Rate × Time.

Front

What does a graph representing distance over time show?

Back

It shows how far an object has traveled over a specific period.

Front

If a person travels 5 m in 5 seconds, what is their rate?

Back

Rate = Distance / Time = 5 m / 5 s = 1 m/s.

Front

What is the formula to find the missing value in a table of rates?

Back

Use the formula: Missing Value = Known Value × (Rate / Known Rate).

Front

In a table showing work hours and earnings, how do you find the missing earnings?

Back

Multiply the number of hours worked by the hourly wage.

Front

What does a slope on a distance-time graph represent?

Back

The slope represents the speed or rate of movement of the object.

Front

If a graph shows an object traveling 10 m in 20 seconds, what is the average speed?

Back

Average Speed = Total Distance / Total Time = 10 m / 20 s = 0.5 m/s.

Front

What is the significance of the y-intercept in a distance-time graph?

Back

The y-intercept represents the starting position of the object at time zero.

Front

How can you determine the total distance from a distance-time graph?

Back

By calculating the area under the graph line over the time interval.
