Read the following link that explains what speed is and how it is calculated. Notice the difference between speed and velocity.

1. Calculate the snails average speed for the journey.
2. What was the snails average speed between seconds 5 and 10?
3. When did the snail stop moving?
4. How far had the snail travelled after 32 seconds?
5. How long did it take the snail to travel 7 cm?
6. When was the snail moving fastest? How do you know?

We can also figure out time and distance by rearranging the speed formula:
distance = time x speed
time = distance / speed
Try some of the following word problems:
