Distance-Time Graphs

_______ _____

is what you get when you divide the total distance an object travels by the total time it takes.

S= d/t

• Average Speed

• Average Distance

• Average Time

What formula would you use?

A girl runs 100m in 12.5sec, calculate her average speed

• T = D / S

• S = D / T

• D = S x T

What formula would you use?

How long did it take for a car traveling at 35 m/s to go 75,000 meters?

• T = D / S

• S = D / T

• D = S x T

What formula would you use?

A tennis ball travels at 40 m/s, how far did it travel in 1.5 seconds?

• T = D / S

• S = D / T

• D = S x T
