Directions:
Use the equation above to answer the following questions. Show your work and
include the units.

1. A football
field is about 100 m long. If it takes a person 20 seconds to run its length,
how fast (what speed) were they running?

2. The pitcher’s
mound in baseball is 85 m from the plate. It takes 4 seconds for a pitch to
reach the plate. How fast is the pitch?

3. If you drive
at 100 km/hr for 6 hours, how far will you go?

4. If you run a t
12 m/s for 15 minutes, how far will you go?

5. Every summer I
drive to

6. A bullet
travels at 850 m/s. How long will it take a bullet to go 1 km?

7. Every winter I
fly home to

8. The fastest train
in the world moves at 500 km/hr. How far will it go in 3 hours?

9. How long will
it take light moving at 300,000 km/s to reach us from the sun? The sun is
15,000,000 km from earth.

10. It is 21,000
kilometers around the earth and the earth rotates in 24 hrs. How fast is it
rotating?

11. A car goes from 0 to 100 km/hr in 10 seconds.
What is its acceleration?

12. A bus slams on its breaks and goes from 30
km/hr to 15 km/hr in 4 seconds. What is its acceleration?
