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

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

The unit for Distance is miles The unit for Time is hours So what is the unit for speed? 345018 mph miles per hour

The unit for Distance is kilometres The unit for Time is hours So what is the unit for speed? 345018 km/h kilometres per hour

The unit for Distance is metres The unit for Time is seconds So what is the unit for speed? 345018 m/s metres per second The speed of sound is 330 m/s. This is called Mach 1.

What speed? 1 hour to travel 20 km So Speed = 20 km/h Distance – Time Graph 1 2 10 20 30 40 50 Distance (km) Time (hours) 1 hour to travel 20 km What speed? So Speed = 20 km/h

What speed? 2 hours to travel 30 miles So Speed = 15 mph ? Distance – Time Graph 1 2 10 20 30 40 50 Distance (miles) Distance (miles) ? Time (hours) 2 hours to travel 30 miles So Speed = 15 mph What speed?

What was the speed for the first part of the journey? Distance – Time Graph 1 2 10 20 30 40 50 Distance (km) Time (hours) What was the speed for the first part of the journey? 10 km in 1 hour, so 10km/h. ¼ of an hour (15 minutes) 2¾ hours (2 hours 45 minutes) How long did it take to run 40 km? How long did she stop for? Approximately 7½ kilometres. How far in ¾ of an hour?
