  1. Mathsercise-C Graphs 2 Ready? Here we go! You will need to print out the graphs to work on – Click Here! Graph Prints

  2. i) Speed = distance/time The distance is 26km, but the time is 0.5 hours (30 minutes), So the speed is… 26/0.5 = 52 km/h This is part of a travel graph of Mo’s journey from his house to the Sports Hall and Back 30 28 26 24 22 20 i) Work out Mo’s speed for the first 30 minutes of his journey. 18 16 ii) Time = distance/speed Time = 26/60 hours Because the speed is 60km per hour, this is 1km per minute! So the time taken will be.. 26 minutes! Distance in KM from Mo’s House 14 12 ii)Mo spent 10 Mins at the Sports Hall and then travelled home at 60km/h. Complete the travel graph 10 8 6 4 2 65 0 5 10 15 20 25 30 35 40 45 50 55 60 70 75 80 1 Time in Minutes Question 2 Graphs 2 Answer

  3. The horizontal line means that the girl has stopped. How long is the line? A girl left home at 12 noon to go for a cycle ride. The graph shows part of the journey. 30 28 26 24 22 20 i) At 12.30pm, the girl stopped for a rest – for how long? 18 16 Distance from home in KM 14 ii)The girl stopped for another hour at 2pm, then she cycled home and it took her 1hr 30 mins.
