:

30 What’s the speed limit? At this speed, how far would you travel in 1 hour? in 2 hours? in ½ an hour? in 10 minutes?

:

70 If I travel 70 miles in 1 hour, what’s my speed? If I travel 25 miles in ½ an hour, what’s my speed? 50 If I travel 15 miles in ¼ of an hour, what’s my speed? 60 If I travel 10 miles in ¼ of an hour, what’s my speed? 40

Slide 9:

The unit for Distance is miles The unit for Time is hours So what is the unit for speed? miles per hour mph

Slide 10:

The unit for Distance is kilometres The unit for Time is hours So what is the unit for speed? kilometres per hour km/h

Slide 11:

metres per second The unit for Distance is metres The unit for Time is seconds So what is the unit for speed? The speed of sound is 330 m/s. This is called Mach 1. m/s

Slide 12:

Time (hours) Distance (km) Distance – Time Graph What speed? 1 hour to travel 20 km So Speed = 20 km/h

Slide 13:

Time (hours) Distance (miles) Distance – Time Graph What speed? 2 hours to travel 30 miles So Speed = 15 mph Distance (miles) ?

Slide 14:

Now do Exercise 1, Q. 1, 2 & 3 (HSDU Support Materials)

Slide 15:

Time (hours) Distance (km) Distance – Time Graph How far in ¾ of an hour? Approximately 7½ kilometres. What was the speed for the first part of the journey? 10 km in 1 hour, so 10km/h. How long did she stop for? ¼ of an hour (15 minutes) How long did it take to run 40 km? 2¾ hours (2 hours 45 minutes)
