Calculating Speed

What is the formula for calculating average speed?

• Total distance traveled / Total time taken

• Total distance traveled + Total time taken

• Total distance traveled - Total time taken

• Total distance traveled * Total time taken

If a car travels 200 miles in 4 hours, what is its average speed?

• 150 miles per hour

• 100 miles per hour

• 50 miles per hour

• 25 miles per hour

How do you graph speed vs. time?

• Plot time on the y-axis and speed on the x-axis

• Graph distance on the y-axis and time on the x-axis

• Use a bar graph instead of a line graph

• Plot speed on the y-axis and time on the x-axis

What does the slope of a speed vs. time graph represent?

• Time

• Velocity

• Acceleration

• Distance

How are speed and distance related?

• Speed is unrelated to distance

• Distance is the result of speed divided by time

• Speed is the ratio of distance traveled to the time taken to travel that distance.

• Speed is the result of distance divided by time

If a car travels at a speed of 60 mph, how far will it travel in 2.5 hours?

• 75 miles

• 100 miles

• 150 miles

• 200 miles

What does the slope of a position vs. time graph represent?

• Distance

• Acceleration

• Time

• Velocity

How do you calculate speed from a position vs. time graph?

• Find the slope of the graph

• Count the number of lines on the graph

• Measure the area under the graph

• Find the y-intercept of the graph

If an object travels 100 meters in 20 seconds, what is its speed?

• 50 m/s

• 10 m/s

• 5 m/s

• 200 m/s

How do you calculate the average speed from a distance vs. time graph?

• Count the number of points on the graph

• Find the area under the graph

• Divide the distance by the time

• Find the slope of the line on the graph
