How can you identify a constant speed on a graph?

• By a zigzag line

• By a dotted line

• By a straight line

• By a curved line

What is the first step in calculating constant speed from a graph?

• Draw a line from the start to the end of the journey

• Draw a line from the end to the time axis

• Draw a line from the start to the time axis

• Draw a line from the end to the distance axis

If the distance traveled at constant speed is 500 meters in 30 seconds, what is the speed in meters per second?

• 10 meters per second

• 15 meters per second

• 16.7 meters per second

• 20 meters per second

What is the equivalent speed in kilometers per hour if you travel 16.7 meters per second?

• 60 kilometers per hour

• 50 kilometers per hour

• 70 kilometers per hour

• 80 kilometers per hour

What happens to the graph line when you come to a stop but time continues?

• The line goes downwards

• The line goes upwards

• The line becomes flat

• The line becomes zigzag

What is the final step in calculating the distance traveled at constant speed from a graph?

• Multiply the initial distance by the final distance

• Add the initial distance to the final distance

• Divide the initial distance by the final distance

• Subtract the initial distance from the final distance
