3. The distance from Liverpool to Prague is 1200 km.
A flight from Liverpool to Prague lasts 4 hours.
Work out the average speed of the aeroplane.

Speed is distance/ time so

1200/ 4 = 300

Average speed is 300km/h.

Hope this helps! Any questions let me know :)

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
