What is average speed?
total distance traveled by the object in a particular time interval
What is the formula for average speed?
s=d/t
If a train travels 120 miles in 2 hours, what is its average speed?
60 mph
How can you represent average speed on a graph?
On a distance-time graph, average speed is represented by the slope of a line connecting the starting and ending points of the motion, as it calculates the total distance traveled divided by the total time taken.
How is average speed calculated?
s=d/t
If a car travels 300 miles in 5 hours, what is its average speed?
60mph
A person walks 3 miles in 1 hour. What is their average speed?
3 mph
What does a steeper line on a distance-time graph indicate?
faster speed
What are the units for average speed?
km/h
mph
m/s
...
If a runner completes a 10 km race in 50 minutes, what is their average speed in km/h?
12.05 km/h
If you drive 60 miles at 30 mph and then 60 miles at 60 mph, what is your average speed for the whole trip?
40 mph
If a distance-time graph shows a straight line, what does that mean about speed?
the speed of the object is constant
What is the difference between average speed and instantaneous speed?
Average speed is the total distance traveled by an object divided by the total time taken, representing the overall pace of motion over a period of time, while instantaneous speed is the speed of an object at a specific moment in time, essentially a snapshot of its speed at that exact instant
How do you rearrange the average speed formula to find distance?
d=s*t
A plane flies for 2 hours at 500 mph. How far does it travel?
1000 miles
How can you calculate average speed from a distance-time graph?
Find the total distance traveled on the graph, then divide that distance by the total time taken; essentially, you are calculating the slope of the line connecting the starting and ending points of the graph, as the slope represents the average speed on a distance-time graph.
Why is average speed important in real life?
provides a practical way to estimate how long it will take to travel a certain distance
If a bike travels at different speeds, how can you find the overall average speed?
calculate the total distance traveled and divide it by the total time taken to cover that distance
If you jog for 30 minutes at 4 mph, how far do you go?
2 miles
How would you interpret a graph showing varying speeds?
A graph showing varying speeds indicates that an object is not moving at a constant speed, meaning its velocity is changing over time; a steep slope on the graph represents a rapid change in speed (acceleration or deceleration), while a flat line signifies constant speed, and the direction of the slope shows if the object is speeding up or slowing down.
