First time using quizizz lessons​

1. ​Make sure you answer all of the questions. We can see the leader board at the end and who answered the most correct.

2. ​There will be points on classdojo for who gets the most correct.

3. ​This is to review for your mini quiz tomorrow! If you want, you can also write your answers in your book or your notebook to study later. The questions come from Pg. 134

Fill in the Blanks

A red car travels 120 km in one hour. A blue car travels 130 km in the same time. Which car has the greater average speed?

Fill in the Blanks

Runner A takes 45 s to run 400 m. Runner B takes 48 s to run the same distance. Which runner has the greater average speed?

Fill in the Blanks

A bus travels a distance of 100 km in 2.5 h. Calculate its average speed. Give your answer in km/h, and include the units in your answer.

Fill in the Blanks

A driver can work out her average speed using the instruments in her car. The picture shows the clock and the distance meter at the beginning of a journey, and at the end. The distance meter gives the total distanced travelled by the car in its lifetime, in km.

How much time has passed between the beginning and end of the journey?

Fill in the Blanks

The picture shows the clock and the distance meter at the beginning of a journey, and at the end. The distance meter gives the total distanced travelled by the car in its lifetime, in km.

How far has the car travelled in this time?

Fill in the Blanks

The picture shows the clock and the distance meter at the beginning of a journey, and at the end. The distance meter gives the total distanced travelled by the car in its lifetime, in km.

Calculate the car’s average speed during the journey. Include units in your answer

Multiple Choice

A train is traveling at an average speed of 150 km/h. How far will it travel in 2.4 hours? Show your work.

• Distance = Speed / Time

  Distance = 150km/h / 2.4h

  Distance = 360km

• Distance = Speed / Time

  Distance = 150km/h / 2.4h

  Distance = 62.5km

• Distance = Speed x Time

  Distance = 150km/h x 2.4h

  Distance = 62.5km

• Distance = Speed x Time

  Distance = 150km/h x 2.4h

  Distance = 360km

Multiple Choice

A train is traveling at an average speed of 150 km/h. How long will it take to travel between two stations 525 km apart?

Show your work.

• Time = Speed / Distance

  Time = 0.3h

• Time = Distance / Speed

  Time = 3.5h

• Time = Speed x Distance

  Time = 3.5h

• Time = Distance / Speed

  Distance = 0.3h

Multiple Choice

Which graph represents the journey of a car moving at a steady speed?

• A

• B

• C
