  1. Time Distance Speed Calculating Distance Calculating Time Calculating Speed www.mathsrevision.com Mixed Problems Created by Mr. Lafferty Maths Dept.

  2. Starter Questions Find the area and perimeter of the rectangle. 9 m www.mathsrevision.com 4 m Created by Mr. Lafferty Maths Dept.

  3. Distance Working Out Distance Learning Intention Success Criteria • Understand the distance formula. • 1. We are learning how to work out simple distance. • 2. Apply the formula to calculate simple distance. www.mathsrevision.com Created by Mr. Lafferty Maths Dept.

  4. Distance Working out Distances Imagine you were travelling in a train at a steady speed of 80km/hr. In 1 hour you travel : 80 x 1 = 80 km In 2 hours you travel : 80 x 2 = 160 km In 3 hours you travel : 80 x 3 = 240 km www.mathsrevision.com Can you guess what the formula is : in symbols Created by Mr. Lafferty Maths Dept.

  5. Distance Example : A racing car travelled at 50 km/hr. What is the distance covered in 6 hours ? Working www.mathsrevision.com Created by Mr. Lafferty Maths Dept.

  7. Starter Questions • 692 ÷ 1000 • 10% of £19 • 3. Name this triangle www.mathsrevision.com Created by Mr. Lafferty Maths Dept.

  8. Time Learning Intention Success Criteria • Understand the time formula. • 1. We are learning how to calculate time taken. • 2. Apply the formula to calculate simple time taken . www.mathsrevision.com Created by Mr. Lafferty Maths Dept.

  9. Time Working Out Time Imagine you flew 800 miles to Paris and the average speed of the plane was 200 miles/hr. To travel 200 miles takes 1 hour : To travel 800 miles takes : 800 ÷ 200 = 4 hours www.mathsrevision.com Can you guess what the formula is : in symbols Created by Mr. Lafferty Maths Dept.

  10. Time Ex : Tony ran 400 metres at an average speed of 5m/s. How long did he take to complete the race. Working www.mathsrevision.com Created by Mr. Lafferty Maths Dept.

  14. Speed Working Out Speed Imagine you sailed 45 kilometres between two islands and it took 3 hours. In 3 hours you travel : = 45 km In 1 hour you travel : 45 ÷ 3 = 15 km This means your speed is : 15km/hr www.mathsrevision.com Can you guess what the formula is : in symbols Created by Mr. Lafferty Maths Dept.
