• You leave your house and jog the 1000m to the club. You arrive 5 minutes later.
• You exchange stamps and chat for 1 hour, then leave for home. It takes you 10 minutes.
• Distance from home (m)
• Time (minutes)
• 200
• 400
• 600
• 800
• 1000
• 0 10 20 30 40 50 60 70 80
• 2. Decide how many points to plot.
• You are at home getting ready to go out to your stamp collecting club.
• You leave your house and jog the 1000m to the club. You arrive 5 minutes later.

Slide 5 - Constant speed

• distance
• time
• fast

• slow

Slide 6 - Calculate each racer’s average speed over the race.
