# Speed

```Make your foldable, after finishing
Fold your paper in half like a hotdog and
then into 3 sections.
Label each section like the example above.
SPEED
What do you need to know to calculate this
horse’s average speed?
Definition
Speed is the distance traveled
by an object divided by the
time taken to travel that
distance.
average speed= total distance
total time
Let’s Solve a Problem together!
An athlete swims a distance from one end
of a 50m pool to the other end in a time of
25s. What is the athlete’s average speed?
- Step one: Write the equation for average speed.
- speed= total distance
total time
- Step two: Replace the total distance and total time
with the values given, and solve.
- speed= 50m
25s
=2 m/s
This is how your foldable will
begin to look.
Kira jogs to a store 72 m away in a time
of 36 s. What is Kira’s average speed?
Speed=distance
time
=72m
36s
=2m/s
If you travel 7.5 km and walk for 1.5 h,
Speed = distance
time
= 7.5km
1.5h
= 5 km/h
An airplane traveling from San Francisco to
Chicago travels 1260 km in 3.5 h. What is the
airplane’s average speed?
Speed = distance
time
= 1260 km
3.5 h
= 360 km/h
Velocity
Velocity describes both speed and
direction.
Example:
If you say that an airplane’s velocity is
600km/h, you would not be correct.
But you could say the plane’s
velocity is 600km/h south.
