At a Snail's Pace:
KEY CONCEPT
A change in position in a certain amount of time is motion 
Speed is the rate at which an object moves 
Velocity is speed in a given direction
A snail move at an average speed of 5 centimeters per minute (5cm/min).  Individual snails, however, may move at somewhat faster or slower speeds.  To prove this point, three snails decided to have a race.  They agreed to race the length of a meterstick from 0 centimenters to 100 centimeters.  Thye lined up the meter stick from east to west on a smooth patch of grass.  At the finish line, the place some tasty lettuce leaves for the winning snail to eat.

The race begins at 10 am sharp.  Figure 1 shows the lineup of the snails.

Figure 2 shows the position of the snails after the first 5 minutes of the race.  (d1)

Figure 3 shows the position of the snails after the second 5 minutes of the race  (d2)

Questions re garding the race

1.  Determine the distance that each snail traveled between 10:05 am  and 10;10 am
                                               
Snail 1 
 
Snail 2 
 
Snail 3 
 
Distance @ 10:10 - distance @ 10:05
Distance @ 10:10 - distance @ 10:05
Distance @ 10:10 - distance @ 10:05

2.  Calculate the average speed for each snail between 10:05 am and 10:10 am
                                                
Snail 1 
 
Snail 2 
 
Snail 3 
 
Total distance /total time
Total time = 10:10-10:05
 
Total distance /total time
Total time = 10:10-10:05
 
Total distance /total time
Total time = 10:10-10:05

4.  A person watching the race notice that at exactly 10:04 am an ant wandered onto the snails' meterstick.  The ant  crawled onto the 94 cm mark and reach the 50 cm mark at exactly 10:05 am.  What was the velocity of the ant?
