  1. 10 March 2025 Speed, distance and time LO: To solve problems about speed, distance and time. www.mathssupport.org

  2. Average speed The average speed s is calculated by dividing the total distance travelled d by the total time taken t. distance travelled (d) time taken (t) Average speed (s)= A mnemotechnic to remember this formula d s t www.mathssupport.org

  3. Average speed To calculate the total time taken t. distance travelled (d) time taken (t) = Average speed (s) A mnemotechnic to remember this formula d s t www.mathssupport.org

  4. Average speed To calculate the total distance travelled d. time taken (t) distance travelled (d) = Average speed (s) A mnemotechnic to remember this formula d s t www.mathssupport.org

  5. Average speed The unit for Distance is metres The unit for Time is seconds So what is the unit for speed? 345018 m/s www.mathssupport.org

  6. Average 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 www.mathssupport.org

  7. Average speed 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 www.mathssupport.org

  8. 30 What s the speed limit? At this speed, how far would you travel in 1 hour? in 2 hours? in an hour? in 10 minutes? www.mathssupport.org

  9. 70 50 60 40 If I travel 25 kilometres in an If I travel 15 kilometres in of an If I travel 10 kilometres in of an If I travel 70 kilometres in 1 hour, what s my speed? hour, what s my speed? hour, what s my speed? hour, what s my speed? www.mathssupport.org

  10. Average speed d s t Clark runs a 42.2 km marathon in 3 hours 5 minutes and 17 seconds. Find his average speed in Km/h d t d = 42.2 km 5 60 3600 42.2 s = s = 5 17 3 + + 60 3600 17 + 3 + t = hours s 13.7 km/h Clark s average speed is about 13.7 km/h www.mathssupport.org

  11. Average speed d s t Biathlete Jo cycles 60 km at a speed of 30 km/h, and then runs another 15 km at a speed of 10 Km/h. Find: (a) The total time Jo trains for (b) The average speed for Jo s training session. s = d t total distance = 60km + 15km = 75 km d s t = cycling t = 60 km 30 km/h t = 2 hours t = d s t = 15 km 10 km/h total time = 3.5 h running 75km 3.5h s = s 21.4 km/h t = 1.5 hours total time = 2 h + 1.5 h = 3.5 hours www.mathssupport.org
