1) 'Speed Distance Time' is the formula used to explain the relationship between speed, distance and time ('time' is how long it takes to travel a particular distance at a certain speed). Speed = distance ÷ time. Or we can say: distance divided by speed will give you the time. If you know two of the inputs you can work out the third. a) OK b) Tell me more! 2) If a car travels for 2 hours and covers 120 kilometres, we can work out speed as: a) 120 ÷ 2 = 60 kilometres per hour b) 120 x 2 = 240 kilometres per hour 3) The 'Speed Distance Time Triangle' is a way to describe the relationship between speed, distance and time. From this triangle we can work out how to calculate each measure: We can ‘cover up’ what we are trying to find and the formula triangle tells us what calculation to do. What is the formula for working out the speed? a) Speed = Distance ÷ Time b) Speed = Time ÷ Distance c) Speed = Distance x Speed 4) If you move 50 metres in 10 seconds, what is your speed? a) 5 metres per second b) 5 metres per hour c) 500 metres per second 5) If a car travels 400m in 20 seconds, how fast is it going? a) 20m per second b) 20m per hour c) 80m per second 6) The 'Speed Distance Time Triangle' is a way to describe the relationship between speed, distance and time. From this triangle we can work out how to calculate each measure: We can ‘cover up’ what we are trying to find and the formula triangle tells us what calculation to do. What is the formula for working out the time? a) Time = Distance ÷ Speed b) Time = Speed ÷ Distance c) Time = Distance x Speed 7) A car travels 300 km at a speed of 100 km/hr. How much time did it take for the car to complete the trip? a) 3 hours b) 30 hours c) ⅓ of an hour 8) Emily rides her bike at a speed of 10 km/hr. How long will she take to travel a distance of 5 km? a) half an hour b) 30 minutes c) one hour d) 40 minutes 9) The 'Speed Distance Time Triangle' is a way to describe the relationship between speed, distance and time. From this triangle we can work out how to calculate each measure: We can ‘cover up’ what we are trying to find and the formula triangle tells us what calculation to do. What is the formula for working out the distance? a) Distance = Speed x Time b) Distance = Speed ÷ Time c) Distance = Time ÷ Speed 10) Josh walks at a speed of 4km/hr. How far will he travel if he walks for 1.5 hours? a) 6 km b) 5 km c) 7 km 11) Yesterday I drove for 9 hours at a speed of 120 km/hr. How far did I drive? a) 1,080 km b) 1,080 m c) 1,008 km 12) A dragonfly travelled south 110 metres in 4 minutes. What was the speed of the dragonfly? a) 27.5 m/min b) 27.5 m/hr c) 25.7 km/hr d) 25.7 m/min 13) A police car travelled 30km in 0.5 hours. Which one shows the working out to calculate its speed? a) b) 14) A police car travelled at 30km in 0.5 hours. What was its speed? a) 60 km/hr b) 60 km/s c) 60 m/hr
